[PATCH] Remove security_inode_post_create/mkdir/symlink/mknod hooks

This patch removes the inode_post_create/mkdir/mknod/symlink LSM hooks as
they are obsoleted by the new inode_init_security hook that enables atomic
inode security labeling.

If anyone sees any reason to retain these hooks, please speak now.  Also,
is anyone using the post_rename/link hooks; if not, those could also be
removed.
