nfsd4: hash closed stateid's like any other
Look up closed stateid's in the stateid hash like any other stateid
rather than searching the close lru.
This is simpler, and fixes a bug: currently we handle only the case of a
close that is the last close for a given stateowner, but not the case of
a close for a stateowner that still has active opens on other files.
Thus in a case like:
open(owner, file1)
open(owner, file2)
close(owner, file2)
close(owner, file2)
the final close won't be recognized as a retransmission.
