[PATCH 2/2] test/reorder: fix double free of drained buffers

[Volodymyr Fialko <vfialko@marvell.com>]

Set to zero array of drained buffers after free, to prevent freeing them
one more time.
Discovered with enabled `RTE_LIBRTE_MEMPOOL_DEBUG`.

Fixes: ecd867faa860 ("test/reorder: fix freeing mbuf twice")
