Given that you don't actually introduce a per-ag inumbers interface in
this series I'd prefer if you just refactor the inumbers code to
add a helper that operates on an AG with xfs_inumbers moving on to
the next one, but not adding the xfs_aginumbers structure that just
makes the move less obvious for now.
