[libvirt] [PATCHv2 2/2] qemu: make PCI multifunction support more manual

[Laine Stump]

Okay, I made Eric's suggested changes and pushed.

This means that multifunction will no longer be automatically turned on 
for function 0. This necessitates a change in, e.g. USB 2.0 configs, 
where multiple functions on a slot are used - you will need to add 
"multifunction='on'" to the <address> element of the device on function 0.
