qemu: Honor the original properties of PCI device when detaching

Browse Source 
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.
