The b_frozen_data allocation should not be failed during journal
committing process, otherwise jbd2 will abort.
Since commit 490c1b444ce653d("jbd2: do not fail journal because of
frozen_buffer allocation failure") already added '__GFP_NOFAIL' flag
in do_get_write_access(), just add '__GFP_NOFAIL' flag for all allocations
in jbd2_journal_write_metadata_buffer(), like 'new_bh' allocation does.
Besides, remove all error handling branches for do_get_write_access().

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.
