[dpdk-dev] [PATCH] app/testpmd: add to call detach for vdev when quitting

[zhiyong . yang]

For vdev, just calling rte_eth_dev_close() isn't enough to free all
the resources allocated during device probe, e.g. for virtio-user,
virtio_user_pmd_remove(), i.e. the remove() method of a vdev driver,
needs to be called to unlink the socket file created during device
probe. So this patch calls the rte_eth_dev_detach() for vdev when
quitting testpmd.
