virtio-devices: vhost_user: net: Move control queue back

Browse Source 
We thought we could move the control queue to the backend as it was
making some good sense. Unfortunately, doing so was a wrong design
decision as it broke the compatibility with OVS-DPDK backend.

This is why this commit moves the control queue back to the VMM side,
meaning an additional thread is being run for handling the communication
with the guest.
