virtio-net: Add only one queue pair when realizing

Browse source 
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: f9d6dbf0bf ("virtio-net: remove virtio queues if the guest doesn't support multiqueue")
