net: ena: make ena rxfh support ETH_RSS_HASH_NO_CHANGE
commit 470793a78ce344bd53d31e0c2d537f71ba957547 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.
