virtio-pci: S3 support
There's no difference in supporting S3 and S4 for virtio devices: the vqs have to be re-created as the device has to be assumed to be reset at restore-time. Since S4 already handles this situation, we can directly use the same code and callbacks for S3 support. Signed-off-by: Amit Shah <amit.shah@redhat.com>
