wifi: mac80211: Check if we had first beacon with relevant links

Browse source 
If there is a disassoc before the fisrt beacon we need to protect a
session for the deauth frame. Currently we are checking if we had a
beacon in the default link, which is wrong in a MLO connection and
link id != 0.
Fix this by checking all the active links, if none had a beacon then
protect a session.
If at least one link had a beacon there is no need for session
protection.
