Jens Freimann a4270ea4ff net/virtio: check head desc with correct wrap counter 
In virtio_pq_send_command() we check for a used descriptor
and wait in an idle loop until it becomes used. We can't use
vq->used_wrap_counter here to check for the first descriptor
we made available because the ring could have wrapped. Let's use
the used_wrap_counter that matches the state of the head descriptor.

Fixes: ec194c2f18 ("net/virtio: support packed queue in send command")
