Get rid of confusing usage of cu->bb in BKE_object_minmax

Curve-type objects now always does have object'level
bounding box, meaning cu->bb wouldn't evenr used in
BKE_object_minmax.

So zapping this confusing check for whether ob->bb
exists, which is always truth. Makes it easier to
follow what cu->bb is for and what ob->bb is for.
