sfc: don't report RX hash keys to ethtool when RSS wasn't enabled
If we failed to set up RSS on EF10 (e.g. because firmware declared
RX_RSS_LIMITED), ethtool --show-nfc $dev rx-flow-hash ... should report
no fields, rather than confusingly reporting what fields we _would_ be
hashing on if RSS was working.
Fixes: dcb4123cbec0 ("sfc: disable RSS when unsupported")
