This value must be returned to the user through the BIO iter sector. This is done in 2 places: in blk_complete_request() and in blk_update_request(). Introduce the inline helper function blk_zone_update_request_bio() to avoid duplicating this BIO update for zone append requests, and to compile out this helper call when CONFIG_BLK_DEV_ZONED is not enabled.
