sunrpc: don't keep expired entries in the auth caches.
currently expired entries remain in the auth caches as long
as there is a reference.
This was needed long ago when the auth_domain cache used the same
cache infrastructure. But since that (being a very different sort
of cache) was separated, this test is no longer needed.
So remove the test on refcnt and tidy up the surrounding code.
This allows the cache_dequeue call (which needed to be there to
drop a potentially awkward reference) can be moved outside of the
spinlock which is a better place for it.
