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.
