Subject: [PATCH] test/reorder: fix freeing mbuf twice
[ upstream commit ecd867faa860b41a154b3e24f6ea4536562234ab ]
mbufs are being freed twice in error, once in rte_mempool_put_bulk()
and then in rte_reorder_free(). Refactor the code so that we use
rte_reorder_free() to free mbufs in the reorder buffer, and use
rte_pktmbuf_free() to free any unused or drained mbufs.
Fixes: d0c9b58d71 ("app/test: new reorder unit test")
