We don't need to fix this right away (I'll apply the patch w/o dealing
with this), but probably the right thing to do is to deal with
punching a hole in an inline data file by setting the region of the
file to zero --- after all, that's how we handle punching
non-page-aligned regions for extent based files, so we might as well
support inline data files the same way, especially since that should
be a relatively easy change.
