hash: move struct field to keep ABI stable

Browse Source 
In order to keep the ABI consistent with the old hash library,
hash_func_init_val field has been moved, so it remains
at the same offset as previously, since hash_func and
hash_func_init_val are fields accessed by the public function
rte_hash_hash and must keep the same offset as older versions.

Fixes: 48a3991196 ("hash: replace with cuckoo hash implementation")
