Inside test_reorder_insert()
rte_mempool_get_bulk() and rte_mempool_put_bulk() are used
to allocate and free the mbufs and then rte_reorder_free()
is called which again freeing the mbufs using rte_pktmbuf_free().
The mixed use of rte_mempool_put_bulk() and rte_pktmbuf_free()
causing duplicate mbufs to be created when rte_mempool_get_bulk()
is called next in test_reorder_drain().
Since reorder library is taking care of freeing the mbufs
using rte_pktmbuf_free() change UT to allocate mbufs using
rte_pktmbuf_alloc().
Do not mix and match the bulk get/put APIs with
alloc/free APIs which can cause undefined behavior.
