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).
