[libvirt] [PATCHv3 1/1] Assign spapr-vio bus address to ibmvscsi controller

For pseries guest, the default controller model is ibmvscsi controller, this controller only can work on spapr-vio address. This patch is to assign spapr-vio address type to ibmvscsi controller and correct vscsi test case.
