Provide ext4_journal_ensure_credits_fn() function to ensure transaction has given amount of credits and call helper function to prepare for restarting a transaction. This allows to remove some boilerplate code from various places, add proper error handling for the case where transaction extension or restart fails, and reduces following changes needed for proper revoke record reservation tracking.

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.
