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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
