Luckily not, because only "real" regions (not aliases and containers)
end up in a FlatView.  So you can do object_unparent on aliases and
containers.  It's ugly and should be avoided, but not buggy.

There's only three cases (VFIO, for which patches have been posted and
reviewed already, plus other two in PCI) that have to be modified.
