    net: ethtool: remove duplicate defines for family info

    Commit under fixes switched to uAPI generation from the YAML
    spec. A number of custom defines were left behind, mostly
    for commands very hard to express in YAML spec.

    Among what was left behind was the name and version of
    the generic netlink family. Problem is that the codegen
    always outputs those values so we ended up with a duplicated,
    differently named set of defines.

    Provide naming info in YAML and remove the incorrect defines.
