net: ena: make ena rxfh support ETH_RSS_HASH_NO_CHANGE
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.
Fixes: 1738cd3ed342 ("net: ena: Add a driver for Amazon Elastic Network Adapters (ENA)")
