On completion of a zone append request, the request sector indicates the location of the written data. 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.

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 reStructuredText 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.
