This patch fixes buffer overflow reported by ASAN,
please reference https://bugs.dpdk.org/show_bug.cgi?id=818
Some tests for the rte_hash table use the rte_jhash_32b() as
the hash function. This hash function interprets the length
argument in units of 4 bytes.
This patch divides configured key length by 4 in cases when
rte_jhash_32b() is used.
