NFSv4: Fix nfs_clear_verifier_delegated() for delegated directories

Browse source

If the client returns a directory delegation, then look up all the child
dentries, and clear their 'verifier delegated' bit, unless subject to a
file delegation.

Similarly, if a file delegation is being returned, check if there is a
directory delegation before clearing a 'verifier delegated' bit.
