NFS: Simplify nfs_fhget()
If the inode is being initialised, there is no point in setting flags such as NFS_INO_INVALID_ACCESS, NFS_INO_INVALID_ACL or NFS_INO_INVALID_DATA since there are no cached access calls, acls or data caches to invalidate. Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
