Update the device link of the QemuConsole, so it points to the virtio-gpu-pci or virtio-vga device instead of virtio-gpu-device. This is needed because we want to find the device by id, for example for input routing, and the id specified on the command line is attached to the pci proxy, not the virtio device.
