vdpa: store x-svq parameter in VhostVDPAState
CVQ can be shadowed two ways: - Device has x-svq=on parameter (current way) - The device can isolate CVQ in its own vq group QEMU needs to check for the second condition dynamically, because CVQ index is not known before the driver ack the features. Since this is dynamic, the CVQ isolation could vary with different conditions, making it possible to go from "not isolated group" to "isolated". Saving the cmdline parameter in an extra field so we never disable CVQ SVQ in case the device was started with x-svq cmdline.
