md: raid0 create_strip_zones(): Make two local variables sector-based.
current_offset and curr_zone_offset stored the corresponding offsets as 1K quantities. Rename them to current_start and curr_zone_start to match the naming of struct strip_zone and store the offsets as sector counts. Also, add KERN_INFO to the printk() affected by this change to make checkpatch happy. Signed-off-by: Andre Noll <maan@systemlinux.org> Signed-off-by: NeilBrown <neilb@suse.de>
