[PATCH] xfsprogs: remove unused libxfs helper #defines

[Eric Sandeen <sandeen@redhat.com>]

There are several #defines which aren't used anywhere
in either xfsprogs or the kernel, so remove them from the
libxfs/libxfs_priv.h helper file.

This does leave a few (currently) unused defines in place
if they are still used in the kernel, in the hope that future
libxfs changes might Just Work.
