[virtio] Renumber virtio_pci_region flags
Some of the regions may end up being unmapped, either because they are
optional or because the attempt to map them has failed. Region types
starting at 0 didn't make it easy to test for this condition.
This commit bumps all valid region types up by 1 with 0 having the
implicit 'unmapped' meaning.
