NFS: Make trace_nfs4_setup_sequence() available to NFS v4.0
This tracepoint displays information about the slot that was chosen for the RPC, in addition to session information. This could be useful information for debugging, and we can set the session id hash to 0 to indicate that there is no session. Signed-off-by: Anna Schumaker <Anna.Schumaker@Netapp.com>
