vfio/pci: fix out-of-sync BAR information on reset
When a PCI device is reset, pci_do_device_reset resets all BAR addresses in the relevant PCIDevice's config buffer. The VFIO configuration space stays untouched, so the guest OS may choose to skip restoring the BAR addresses as they would seem intact. The PCI device may be left non-operational. One example of such a scenario is when the guest exits S3. Fix this by resetting the BAR addresses in the VFIO configuration space as well.
