Yingjie Gao d84ed2f971 xfs: fix error returns in CoW fork repair
commit fcf4faba9f upstream.

xrep_cow_find_bad() returns success after the cleanup labels even if
AG setup, btree queries, or bitmap updates failed. This can make
repair continue with an incomplete bad-file-offset bitmap instead of
stopping at the original error.

The force-rebuild path has a related cleanup problem. If
xrep_cow_mark_file_range() fails, the function returns directly and
skips the scrub AG context and perag cleanup.

Let the force-rebuild path fall through to the existing cleanup code
and return the saved error after cleanup.

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.
