xend: Don't allow migrate with assigned PCI devs.
This can potentially cause a whole machine crash, which I think has
been seen in the wild. The case in the wild was caused by xendomains
auto-resuming domains on reboot, so it wasn't even operator error.
There's no sane way to migrate or suspend domains with PCI devs,
so I disallow it completely.
