Seems we would prefer to avoid this ifdef... if we had a function like

	struct pci_dev *pci_physfn(struct pci_dev *virtfn)

as an inline in <linux/pci.h> that just returns NULL if PCI_IOV is not
enabled, then we could write this as

	if (dev->is_virtfn)
		dev = pci_physfn(dev)

without any #ifdef.
