The 'check_async_write' function is a helper used in 'btrfs_submit_metadata_bio' and it checks if asynchronous writing can be used for metadata. Make the function return bool and get rid of the local variable async in btrfs_submit_metadata_bio storing the result of check_async_write's tests. As this is touching all function call sites, also rename it to should_async_write as this is more in line with the naming we use.

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.
