That clear_wpa_sm_for_all_sta() part is covered by an earlier
contribution that addressed a number of compilation issues. Could you
please clarify what that first_sta_seen_mbssid part is about? MBSSID
support can be used without IEEE 802.11be functionality and that
callback is needed in builds that do not define CONFIG_IEEE80211BE. This
does not result in compilation issues in my tests.

This would break wpa_group_first_sta_seen_mbssid() functionality in
builds that do not define CONFIG_IEEE80211BE since it is used without
that define and it is hardcoded to return false if that callback is not
set.
