pci: Fix INTx routing notifier recursion
For some reason we recurse to fire the INTx routing notifier for each
child of a bus, for each possible device of a bus. That means that if
we add a root port, the notifier gets called for that bridge 256
times. If we add an upstream switch behind that root port, 256^2. But
of course we need a downstream switch, 256^3. This starts to be
noticeable. Stop the insanity.
