Jeff Layton bde7dcd778 nfsd: zero out pointers after putting nfsd_files on COPY setup error
[ Upstream commit 1f0001d43d ]

At first, I thought this might be a source of nfsd_file overputs, but
the current callers seem to avoid an extra put when nfsd4_verify_copy
returns an error.

Still, it's "bad form" to leave the pointers filled out when we don't
have a reference to them anymore, and that might lead to bugs later.
Zero them out as a defensive coding measure.
