Filipe Manana 9c4a062a94 btrfs: send: remove stale code when checking for shared extents
After commit 040ee6120c ("Btrfs: send, improve clone range") we do not
use anymore the data_offset field of struct backref_ctx, as after that we
do all the necessary checks for the data offset of file extent items at
clone_range(). Since there are no more users of data_offset from that
structure, remove it.

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.
