This patch fixes the rte_vhost_dequeue_burst return value
when the virtqueue is not ready. Without it, a discrepancy
between the packet array and its size is faced by the caller
of this API when the virtqueue is not ready.

Fixes: 9fc93a1e2320 ("vhost: fix virtqueue access check in datapath")
Cc: stable@dpdk.org
