For vhost-user devices, we don't want to loose the vhost-user protocol feature through the negotiation between guest and device. Since we know VIRTIO has no knowledge of the vhost-user protocol feature, there is no way it would ever be acknowledged by the guest. For that reason, we create each vhost-user device with the set of acked features containing the vhost-user protocol feature is this one was part of the available list. Having the set of acked features containing this bit allows for solving a bug that was happening through the migration process since the vhost-user protocol feature wasn't explicitely enabled.
