The bucket_offset field of bch_backpointer is a 40-bit bitfield, but the bch2_backpointer_swab() helper uses swab32. This leads to inconsistency when an on-disk fs is accessed from an opposite endian machine. As it turns out, we already have an internal swab40() helper that is used from the bch_alloc_v4 swab callback. Lift it into the backpointers header file and use it consistently in both places.

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.
