BACKPORT: wifi: cfg80211/mac80211: separate link params from station params

Put the link_station_parameters structure in the station_parameters
structure (and remove the station_parameters fields already existing
in link_station_parameters).
Now, for an MLD station, the default link is added together with
the station.
