This is to allow the block layer zone reavlidation to check these device characteristics prior to checking all zones of the device. Since blk_queue_max_zone_append_sectors() already caps the device maximum zone append limit to the zone size and to the maximum command size, the max_append value passed to blk_queue_max_zone_append_sectors() is simplified to the maximum number of segments times the number of sectors per page.
