All drivers have been converted. Stop using the rxnfc fallbacks

Joe pointed out in earlier review that in ethtool_set_rxfh()
we need both .get_rxnfc and .get_rxfh_fields, because we need
both the ring count and flow hashing (because we call
ethtool_check_flow_types()). IOW the existing check added
for transitioning drivers was buggy.
