mirror: Rewrite mirror_iteration
The "pnum < nb_sectors" condition in deciding whether to actually copy data is unnecessarily strict, and the qiov initialization is unnecessarily for bdrv_aio_write_zeroes and bdrv_aio_discard. Rewrite mirror_iteration to fix both flaws. The output of iotests 109 is updated because we now report the offset and len slightly differently in mirroring progress.
