net/ena: fix ethtool RSS flow configuration

ena_flow_data_to_flow_hash and ena_flow_hash_to_flow_type
treat the ena_flow_hash_to_flow_type enum as power of two values.

Change the values of ena_admin_flow_hash_fields to be power of two values.

This bug effect the ethtool set/get rxnfc.
ethtool will report wrong values hash fields for get and will
configure wrong hash fields in set.
