The targets that support zoned devices such as dm-zoned, dm-linear, and
dm-crypt do not have an endio function, and even if they do (such as
dm-flakey), they don't modify the bio->bi_iter.bi_sector of the cloned
bio that is used to update the orig_bio's bi_sector in dm_zone_endio
function.
This path is triggered only for the new target dm-po2zone and not for
npo2 zone size devices in general. I will mention this is a prep patch
for the new target because I wouldn't call it a bug per se.
