nfsd: hold reference to delegation when updating it for cb_getattr

Browse source

Once we've dropped the flc_lock, there is nothing that ensures that the
delegation that was found will still be around later. Take a reference
to it while holding the lock and then drop it when we've finished with
the delegation.
