cfg80211: stop tracking authenticated state
To track authenticated state seems to have been a design mistake in cfg80211. It is possible to have out of band authentication (FT), tracking multiple authentications caused more problems than it ever helped, and the implementation in mac80211 is too complex. Remove all this complexity, and let userspace do whatever it wants to, mac80211 can deal with that just fine. Association is still tracked of course, but authentication no longer is. Local auth state changes are thus no longer of value, so ignore them completely. This will also help implement SAE -- asking the driver to do an authentication is now almost equivalent to sending an authentication frame, with the exception of shared key authentication which is still handled completely.
