!1093 vfio-pci: Match specific devices with vendor id and device id

Merge Pull Request from: @did-you-collect-the-wool-today 
 
In probe_vendor_drivers, all registered vendor drivers are traversed.
This is not a good idea. If a vendor driver is not implemented well
enough, it may cause the system to panic. Use the vendor id and
device id to select a proper driver.
The acc live migration driver needs to be adapted.
