Introduce the function blk_rq_is_seq_zoned_write(). This function will be used in later patches to preserve the order of zoned writes that require write serialization. This patch includes an optimization: instead of using rq->q->disk->part0->bd_queue to check whether or not the queue is associated with a zoned block device, use rq->q->disk->queue.
