ethtool: Fix set RXNFC command with symmetric RSS hash

The sanity check that both source and destination are set when symmetric
RSS hash is requested is only relevant for ETHTOOL_SRXFH (rx-flow-hash),
it should not be performed on any other commands (e.g.
ETHTOOL_SRXCLSRLINS/ETHTOOL_SRXCLSRLDEL).

This resolves accessing uninitialized 'info.data' field, and fixes false
errors in rule insertion:
  # ethtool --config-ntuple eth2 flow-type ip4 dst-ip 255.255.255.255 action -1 loc 0
  rmgr: Cannot insert RX class rule: Invalid argument
  Cannot insert classification rule
