vDPA: check VIRTIO_NET_F_RSS for max_virtqueue_paris's presence

Browse Source 
virtio 1.2 spec says:
max_virtqueue_pairs only exists if VIRTIO_NET_F_MQ or
VIRTIO_NET_F_RSS is set.

So when reporint MQ to userspace, it should check both
VIRTIO_NET_F_MQ and VIRTIO_NET_F_RSS.

unused parameter struct vdpa_device *vdev is removed
