PCI: Don't try to restore VF BARs
VF BARs are read-only zero, so updating VF BARs will not have any effect.
See the SR-IOV spec r1.1, sec 3.4.1.11.
Don't update VF BARs in pci_restore_bars().
This avoids spurious "BAR %d: error updating" messages that we see when
doing vfio pass-through after 6eb7018705de ("vfio-pci: Move idle devices to
D3hot power state").
