NFS: Fix NFS4 callback up/down prototypes
Make the nfs_callback_up()/down() prototypes just do nothing if NFS4 is not enabled. Also make the down function void type since we can't really do anything if it fails. Signed-Off-By: David Howells <dhowells@redhat.com> Signed-off-by: Trond Myklebust <Trond.Myklebust@netapp.com>
