[dpdk-dev] [PATCH] net/virtio: fix vectorized Rx queue stuck

When Rx burst size >= Rx queue size, all descriptors in used queue consumed without rearm, the next Rx burst found no new packets and returned directly without rearm as well. This patch rearms available queue at once after rx_burst to avoid vq hungry. Fixes: fc3d66212fed ("virtio: add vector Rx")
