Ugh. This is probably the best one so far, but the whole thing is
really confused.

Why does "stop_bus_device" do a "remove" for VF's at _all_? Why is
everything about those stupid virtual devices so screwed up? Why do we
have separate "stop" and "remove" methods, and then the "stop" does a
remove? WTF?
