I don't think it would be a good idea to replace the ap_max_inactivity
configuration parameter (which applies to every STA in the BSS) with a
value received from RADIUS authentication server for a single STA. It
would be more flexible to store this possible available parameter in
struct sta_info and use it instead of hapd->conf->ap_max_inactivity when
the overriding value is available.
