When doing passthrough of a PCI device for an HVM guest, don't insert

This manifests itself such that the first time a device is passed to a
domain, it succeeds. Subsequent attempts fail unless the device is
unbound from pciback or the machine rebooted.


The commit message looks sensible to me. However this might break
qemu-trad PCI passthrough if I'm not mistaken. What QEMU version are you
using?  Upstream or trad? Have you tested both of them?


qemu-trad. I haven't tested with qemu-upstream.
