If the primary enables the vector Rx/Tx path, the current code would let the secondary always choose the non vector Rx/Tx path. This results to a Rx/Tx method mismatch between primary and secondary process. Werid errors then may happen, something like:
PMD: virtio_xmit_pkts() tx: virtqueue_enqueue error: -14 Fix it by choosing the correct Rx/Tx callbacks for the secondary process. That is, use vector path if it's given.
