dlm: recover locks waiting for overlap replies

When recovery looks at locks waiting for replies, it fails to consider
locks that have already received a reply for their first remote operation,
but not received a reply for secondary, overlapping unlock/cancel.  The
appropriate stub reply needs to be called for these waiters.

Appears when we start doing recovery in the presence of a many overlapping
unlock/cancel ops.
