bcachefs checks for journal stuck conditions both in the journal space calculation code and the journal reservation slow path. The logic in both places is rather tricky and can result in non-deterministic failure characteristics and debug output. In preparation to condense journal stuck handling to a single place, refactor the __journal_res_get() logic into a standalone helper. Since multiple callers into the reservation code can result in duplicate reports, use the ->err_seq field as a serialization mechanism for the debug dump. Finally, add some comments to help explain the logic and hopefully facilitate further improvements in the future.

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.
