Just aggregate the bio allocation code into one helper, so that we can replace 4 call sites. There is one special note for zoned write. Currently btrfs_submit_compressed_write() will only allocate the first bio using ZONE_APPEND. If we have to submit current bio due to stripe boundary, the new bio allocated will not use ZONE_APPEND. In theory this should be a bug, but considering zoned mode currently only support SINGLE profile, which doesn't have any stripe boundary limit, it should never be a problem and we have assertions in place. This function will provide a good entrance for any work which needs to be done at bio allocation time. Like determining the stripe boundary.

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.
