dlm: another call to confirm_master in receive_request_reply
When a failed request (EBADR or ENOTBLK) is unlocked/canceled instead of
retried, there may be other lkb's waiting on the rsb_lookup list for it
to complete. A call to confirm_master() is needed to move on to the next
waiting lkb since the current one won't be retried.
