[ Upstream commit 4cfc7d5a4a01d2133b278cdbb1371fba1b419174 ] After commitb77b4a4815("gfs2: Rework freeze / thaw logic"), the freeze error handling is broken because gfs2_do_thaw() overwrites the 'error' variable, causing incorrect processing of the original freeze error. Fix this by calling gfs2_do_thaw() when gfs2_lock_fs_check_clean() fails but ignoring its return value to preserve the original freeze error for proper reporting. Found by Linux Verification Center (linuxtesting.org) with SVACE.

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.
