Don't ever put Misc objects in levels
Don't ever put Misc objects in levels

If doing restrict after inserting some misc objects, we would get
a level with Misc objects. Ignore them when building levels by
factorizing out a hwloc_take_objects_for_levels() and ignoring some
types there (only Misc for now).
