Subject: cifs: Fix missing fscache invalidation

From: David Howells <dhowells@redhat.com>

commit a07d38afd15281c42613943a9a715c3ba07c21e6 upstream.

A network filesystem needs to implement a netfslib hook to invalidate
fscache if it's to be able to use the cache.

Fix cifs to implement the cache invalidation hook.
