Right, this was because walk_tg_tree (and some friends) were not
available in the FAIR_GROUP && !SMP case. The wreckage used to be a
little more extensive but I just tried it again the last rounds of
clean-up seem to have fixed most of it, the only other problem was
updating the SMP group load stuff in the unthrottle path.

I've rolled the required #ifdef-erry to fix the above up and it's not
horrifying so... dependency removed!
