[dpdk-dev] [v3 PATCH] test_distributor: prevent memory leakages from the pool

[Sarosh Arif <sarosh.arif@emumba.com>]

rte_mempool_get_bulk is used to get bufs/many_bufs from the pool,
but at some locations when test fails the bufs/many_bufs are
not returned back to the pool.
Due to this, multiple executions of distributor_autotest gives the
following error message: Error getting mbufs from pool.
To resolve this issue rte_mempool_put_bulk is used whenever the test
fails and returns.

v2:
remove double freeing of mbufs
v3:
resubmit to run the tests again
