[libvirt] [PATCH] qemu: Honor the original properties of PCI device when detaching
This patch fixes two problems:
1) The device will be reattached to host even if it's not
managed, as there is a "pciDeviceSetManaged".
2) The device won't be reattached to host with original
driver properly. As it doesn't honor the device original
properties which are maintained by driver->activePciHostdevs.
