nfsd: don't destroy client if mark_client_expired_locked fails
If it fails, it means that the client is in use and so destroying it would be bad. Currently, the client_mutex prevents this from happening but once we remove it, we won't be able to do this. Signed-off-by: Jeff Layton <jlayton@primarydata.com> Signed-off-by: J. Bruce Fields <bfields@redhat.com>
