NLM/lockd: Fix a race when cancelling a blocking lock
We shouldn't remove the lock from the list of blocked locks until the CANCEL call has completed since we may be racing with a GRANTED callback. Also ensure that we send an UNLOCK if the CANCEL request failed. Normally that should only happen if the process gets hit with a fatal signal.
