[JFFS2][XATTR] Re-define xd->refcnt as atomic_t
In jffs2_release_xattr_datum(), it refers xd->refcnt to ensure
whether releasing xd is allowed or not.
But we can't hold xattr_sem since this function is called under
spin_lock(&c->erase_completion_lock). Thus we have to refer it
without any locking.
This patch redefine xd->refcnt as atomic_t. It enables to refer
xd->refcnt without any locking.
