Jean-Louis Dupond 524d5ba8c0 qcow2: put discards in discard queue when discard-no-unref is enabled ...

When discard-no-unref is enabled, discards are not queued like it
should.
This was broken since discard-no-unref was added.

Add a helper function qcow2_discard_cluster which handles some common
checks and calls the queue_discards function if needed to add the
discard request to the queue.
