That patch should guarantee that we don't loop forever, and if we are
going to loop that looks like a reasonable way to handle it.

When I start working on what is the most maintainable way to implement
merge my hotplug driver work I will come back and test this.

At the moment it appears that it will at least suffer from detecting a
presence change event with a device showing up. Before pci structure
for the device is removed. I seem to recall some dead locks on the
pciehp work queue hotunplugging a hotplug driver as well.
