[dpdk-dev] [PATCH v2 2/3] hash: fix header for C++

When built in a C++ application, the jhash include fails:
rte_jhash.h:123:22: error:
invalid conversion from ‘const void*’ to ‘const uint32_t*’ [-fpermissive]
const uint32_t *k = key;
^
The cast must be explicit for C++.
Fixes: 8718219a8737 ("hash: add new jhash functions")
