XFS_IFORK_Q is supposed to be a predicate, not a function returning a value. Its usage is in xchk_bmap_check_rmaps is incorrect, but that function only cares about whether or not the "size" of the data is zero or not. Convert that logic to use a proper boolean, and teach the caller to skip the call entirely if the end result would be that we'd do nothing anyway. This avoids a crash later in this series.

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.
