Clean out some cruft that could use an already existing

a bug there -- if allocation/insertion fails then it is
possible that we are left in a lingering state where
mac80211 waits for the AP, cfg80211 waits for mac80211,
but the AP has already replied. Since there's no way to
indicate an internal error, pretend there was a timeout,
i.e. that the AP never responded.

      cfg80211: remove warning in deauth case

we assumed that drivers never give us spurious deauth
frames because they filter them out based on the auth
state they keep track of. This turned out to be racy,
because userspace might deauth while the AP is also
sending a deauth frame, so the warning was removed.

However, in that case we should not tell userspace
about the AP's frame if it requested deauth "first",
where "first" means it came to cfg80211 first.
