xfs: #ifdef out perag code for userspace
The xfs_perag structure and initialization is unused in userspace, so #ifdef it out with __KERNEL__ to facilitate the xfsprogs sync and build. Signed-off-by: Eric Sandeen <esandeen@redhat.com> Reviewed-by: Darrick J. Wong <djwong@kernel.org> Signed-off-by: Darrick J. Wong <djwong@kernel.org>
