In rte_eth_dev_rss_hash_conf_get(), the "rss_key_len" should be

least "hash_key_size" bytes. If these requirements are not met,
the query unreliable.
In rte_eth_dev_rss_hash_update() or rte_eth_dev_configure(), the
"rss_key_len" indicates the length of the "rss_key" in bytes of
the array pointed by "rss_key", it should be equal to the
"hash_key_size" if "rss_key" is not NULL.
This patch overwrites the comments of fields of "rte_eth_rss_conf"
and "RTE_ETH_HASH_FUNCTION_DEFAULT", checks "rss_key_len" in
ethdev level, and documents these changes.

There is no poiint to init dev_info here. Get functoin does it anyway.
