Spec doesn't speak anything about MLO between TDLS peers, we shall 
consider it as not applicable at this point.

Also, seems we need to exclude other sta types such as mesh too, as MLO 
is not applicable to Mesh as well. May be I'll add an exclusive case to 
restrict EMLSR change only for CFG80211_STA_AP_CLIENT.
