This function is exported purely for netdev_wait_allrefs()'s sake and for no other purpose.

In fact, I'd say this is entirely a private functional interface specifically built for generic network interface tear-down.

If you are trying to use this function in another context, that's something you need to discuss with us first before we start peppering it with various assertions.

I am not applying this patch.
