Subject: virtio-net: delete also control queue when TX/RX deleted

Git-commit: d945d9f1731244ef341f74ede93120fc9de35913

https://bugzilla.redhat.com/show_bug.cgi?id=1708480
If the control queue is not deleted together with TX/RX, it
later will be ignored in freeing cache resources and hot
unplug will not be completed.
