qdev->parent_bus is not supposed to be accessed either, there is
qdev_get_parent_bus() as accessor function.

Note that Paolo has a series refactoring the in-place bus init (either
for qdev reset or for QOM reference counting) that you may want to take
into account then.
Having the IPackBus not be a pointer but part of the exposing device
initialized in-place would be desirable long-term but, like some other
issues raised, not a criteria for initial patch acceptance IMO.
