I noticed that when for some reason [1] the probe or auth times
out, wpa_supplicant doesn't realise this and only tries the next
AP when it runs into its own timeout, which is ten seconds, and
that's quite long. Fix this by making mac80211 notify userspace
that it didn't associate.

[1] my wrt350n in mixed B/G/HT mode often runs into this, maybe
it's because one of the antennas is broken off and for whatever
reason it decides to use that antenna to transmit the response
frames (auth, probe); I do see beacons fine so it's not totally
broken. Works fine in pure-G mode.
