Anton Nefedov 90ab48eb07 mirror: do not increase offset during initial zero_or_discard phase ... If explicit zeroing out before mirroring is required for the target image, it moves the block job offset counter to EOF, then offset and len counters count the image size twice. There is no harm but stats are confusing, specifically the progress of the operation is always reported as 99% by management tools. The patch skips offset increase for the first "technical" pass over the image. This should not cause any further harm.
