[libvirt] [PATCH 2/2] conf: nodedev: Set PCI_PHYSICAL_FUNCTION flag more carefully

[Andrea Bolognani <abologna redhat com>]

Instead of setting the flag before parsing the PCI address, set
it afterwards. This ensure we can never end up in a situation
where the flag has been set but pci_dev.physical_function has
not been filled in.
