lsm: move the xfrm hook comments to security/security.c

This patch relocates the LSM hook function comments to the function
definitions, in keeping with the current kernel conventions.  This
should make the hook descriptions more easily discoverable and easier
to maintain.

While formatting changes have been done to better fit the kernel-doc
style, content changes have been kept to a minimum and limited to
text which was obviously incorrect and/or outdated.  It is expected
the future patches will improve the quality of the function header
comments.

  *
- * Security hooks for XFRM operations.
- *
- * @xfrm_policy_alloc_security:
- *	@ctxp is a pointer to the xfrm_sec_ctx being added to Security Policy
- *	Database used by the XFRM system.
- *	@sec_ctx contains the security context information being provided by
- *	the user-level policy update program (e.g., setkey).
- *	@gfp is to specify the context for the allocation.
- *	Allocate a security structure to the xp->security field; the security
- *	field is initialized to NULL when the xfrm_policy is allocated.
- *	Return 0 if operation was successful (memory to allocate, legal
- *	context).
- * @xfrm_policy_clone_security:
- *	@old_ctx contains an existing xfrm_sec_ctx.
- *	@new_ctxp contains a new xfrm_sec_ctx being cloned from old.
- *	Allocate a security structure in new_ctxp that contains the
- *	information from the old_ctx structure.
- *	Return 0 if operation was successful (memory to allocate).
- * @xfrm_policy_free_security:
- *	@ctx contains the xfrm_sec_ctx.
- *	Deallocate xp->security.
- * @xfrm_policy_delete_security:
- *	@ctx contains the xfrm_sec_ctx.
- *	Authorize deletion of xp->security.
- *	Return 0 if permission is granted.
- * @xfrm_state_alloc:
- *	@x contains the xfrm_state being added to the Security Association
- *	Database by the XFRM system.
- *	@sec_ctx contains the security context information being provided by
- *	the user-level SA generation program (e.g., setkey or racoon).
- *	Allocate a security structure to the x->security field; the security
- *	field is initialized to NULL when the xfrm_state is allocated. Set the
- *	context to correspond to sec_ctx. Return 0 if operation was successful
- *	(memory to allocate, legal context).
- * @xfrm_state_alloc_acquire:
- *	@x contains the xfrm_state being added to the Security Association
- *	Database by the XFRM system.
- *	@polsec contains the policy's security context.
- *	@secid contains the secid from which to take the mls portion of the
- *	context.
- *	Allocate a security structure to the x->security field; the security
- *	field is initialized to NULL when the xfrm_state is allocated. Set the
- *	context to correspond to secid. Return 0 if operation was successful
- *	(memory to allocate, legal context).
- * @xfrm_state_free_security:
- *	@x contains the xfrm_state.
- *	Deallocate x->security.
- * @xfrm_state_delete_security:
- *	@x contains the xfrm_state.
- *	Authorize deletion of x->security.
- *	Return 0 if permission is granted.
- * @xfrm_policy_lookup:
- *	@ctx contains the xfrm_sec_ctx for which the access control is being
- *	checked.
- *	@fl_secid contains the flow security label that is used to authorize
- *	access to the policy xp.
- *	@dir contains the direction of the flow (input or output).
- *	Check permission when a flow selects a xfrm_policy for processing
- *	XFRMs on a packet.  The hook is called when selecting either a
- *	per-socket policy or a generic xfrm policy.
- *	Return 0 if permission is granted, -ESRCH otherwise, or -errno
- *	on other errors.
- * @xfrm_state_pol_flow_match:
- *	@x contains the state to match.
- *	@xp contains the policy to check for a match.
- *	@flic contains the flowi_common struct to check for a match.
- *	Return 1 if there is a match.
- * @xfrm_decode_session:
- *	@skb points to skb to decode.
- *	@secid points to the flow key secid to set.
- *	@ckall says if all xfrms used should be checked for same secid.
- *	Return 0 if ckall is zero or all xfrms used have the same secid.
