virtio-net: Add only one queue pair when realizing
Multiqueue usage is not negotiated yet when realizing. If more than one queue is added and the guest never requests to enable multiqueue, the extra queues will not be deleted when unrealizing and leak. Fixes: f9d6dbf0bf6e ("virtio-net: remove virtio queues if the guest doesn't support multiqueue") Signed-off-by: Akihiko Odaki <akihiko.odaki@daynix.com> Signed-off-by: Jason Wang <jasowang@redhat.com>
