QE uses the sim_vdpa device to test this patch and add "ctrl_vq=off"
in the qemu command line. Guest can find this device, there are no any
error messages in guest dmesg, and can migrate successfully.

Since GUEST_ANNOUNCE is emulated the feature bit could be set without
backend support. This happens in the vDPA case.
