NFSv4: Fix a potential CLOSE race
Once the state_owner and lock_owner semaphores get removed, it will be
possible for other OPEN requests to reopen the same file if they have
lower sequence ids than our CLOSE call.
This patch ensures that we recheck the file state once
nfs_wait_on_sequence() has completed waiting.
