xfs: remove superflous inobt macros
xfs_ialloc_btree.h has a a cuple of macros that only obsfucate the code but don't provide any abstraction benefits. This patches removes those and cleans up the reamaining defintions up a little. Signed-off-by: Christoph Hellwig <hch@lst.de> Reviewed-by: Dave Chinner <david@fromorbit.com>
