libqos: expose common virtqueue setup/cleanup functions
The VIRTIO 1.0 code will need to perform additional steps but it will
reuse the common virtqueue setup/cleanup code. Make these functions
public.
Make sure to invoke callbacks via QVirtioBus instead of directly calling
the virtio-pci Legacy versions of these functions.
