nfsd: extra checks when freeing delegation stateids

[ Upstream commit 895ddf5ed4c54ea9e3533606d7a8b4e4f27f95ef ]

We've had some reports of problems in the refcounting for delegation
stateids that we've yet to track down. Add some extra checks to ensure
that we've removed the object from various lists before freeing it.
