mac80211: remove crypto special case for auth frames
The shared key authentication frame that needs to be
encrypted (the third one in the shared key handshake)
is directly encrypted in ieee80211_send_auth and the
IEEE80211_TX_INTFL_DONT_ENCRYPT is set. All others
are not encrypted, so the only way to get to this is
erroneously on no-monitor AP side.
Remove the special case for authentication frames to
fix the AP shared key side when operating without
cooked monitor interfaces -- with cooked monitor the
IEEE80211_TX_INTFL_DONT_ENCRYPT also gets set, so we
never get here -- an AP never encrypts auth frames.
Without this patch, an AP operating in WEP mode with
my no-monitor patches would erroneously encrypt all
authentication frames, instead of none.
