virtio-s390: add a reset function to virtio-s390 devices 

virtio-s390 devices are not being reset when their bus is.  To fix
this, add a reset method that forwards to virtio_reset.  This is
only needed because of the "strange" modeling of virtio devices;
the ->vdev link is being handled manually rather than through qdev.
