xfs: rename xfs_buftarg structure members
In preparation for adding new members to the structure, give these old ones more descriptive names: bt_ssize -> bt_meta_sectorsize bt_smask -> bt_meta_sectormask Signed-off-by: Eric Sandeen <sandeen@redhat.com> Reviewed-by: Brian Foster <bfoster@redhat.com> Reviewed-by: Dave Chinner <dchinner@redhat.com> Signed-off-by: Ben Myers <bpm@sgi.com>
