Subject: [PATCH] virtio-devices: net: Loop over enabled queue pairs when
 activating

In some situations (booting with OVMF) fewer queues will be enabled
therefore we should iterate over the number of enabled queues (as passed
into VirtioDevice::activate()) rather than the number of create tap
devices.

Fixes: #2578
