That makes a lot of sense. So we need both a "blocked, will be back
soon" and "this PCI device is invisible" flags. A device going into
blocked and not coming back would presumably transition into
"invisible". I'm assuming we can't just delete the PCI device because
the kernel needs to know that cell is there for future use/abuse.
