ethtool: Clean up definitions of rule location arrays in RX NFC
Correct the description of ethtool_rxnfc::rule_locs; it is an array
of currently used locations, not all possible valid locations.
Add note that drivers must not use ethtool_rxnfc::rule_locs.
The rule_locs argument to ethtool_ops::get_rxnfc is either NULL or a
pointer to an array of u32, so change the parameter type accordingly.
