net: ena: make ena rxfh support ETH_RSS_HASH_NO_CHANGE
commit 470793a7 upstream. As the name suggests ETH_RSS_HASH_NO_CHANGE is received upon changing the key or indirection table using ethtool while keeping the same hash function. Also add a function for retrieving the current hash function from the ena-com layer.
