net/virtio: fix mbuf port for simple Rx function

Browse Source 
The mbuf->port was was not properly set for the first received
mbufs. Fix this by setting it in virtqueue_enqueue_recv_refill_simple(),
which is used to enqueue the first mbuf in the ring.

The function virtio_rxq_rearm_vec(), which is used to rearm the ring
with new mbufs, is correct and does not need to be updated.

Fixes: cab0461234 ("virtio: fill Rx avail ring with blank mbufs")
