nfsd: fix potential race in nfs4_find_file
The WARN_ON_ONCE check is not terribly useful. It also seems possible
for nfs4_find_file to race with the destruction of an fi_deleg_file
while trying to take a reference to it.
Now that it's safe to pass nfs_get_file a NULL pointer, remove the WARN
and NULL pointer check. Take the fi_lock when fetching fi_deleg_file.
