virtio: pci: check bar values read from virtio config space
virtio pci config structures may in future have non-standard bar
values in the bar field. We should anticipate this by skipping any
structures containing such a reserved value.
The bar value should never change: check for harmful modified values
we re-read it from the config space in vp_modern_map_capability().
Also clean up an existing check to consistently use PCI_STD_NUM_BARS.
