I don't really see value in that, it would only make the implementation
less efficient, because either you follow another pointer (sta->stats)
or you have to look in the other hash table. That's why I prefer
embedding it, we have to do the station hash table lookup anyway.

station dump can just print all attributes that exist, some stations
would have more/different attributes than other stations. But I don't
really think it makes a big difference either way, reusing it would be
fine if the default is to not include the stats-only entries.
