mac80211: avoid spurious deauth frames/messages
With WEXT, it happens frequently that the SME requests an authentication but then deauthenticates right away because some new parameters came along. Every time this happens we print a deauth message and send a deauth frame, but both of that is rather confusing. Avoid it by aborting the authentication process silently, and telling cfg80211 about that. The patch looks larger than it really is: __cfg80211_auth_remove() is split out from cfg80211_send_auth_timeout(), there's no new code except __cfg80211_auth_canceled() (a one-liner) and the mac80211 bits (7 new lines of code).
