vfio/pds: Use proper PF device access helper

The pci_physfn() helper exists to support cases where the physfn
field may not be compiled into the pci_dev structure. We've
declared this driver dependent on PCI_IOV to avoid this problem,
but regardless we should follow the precedent not to access this
field directly.
