     mac80211: fix idle handling sequence

     Corey Richardson reported that my idle handling cleanup
     (commit fd0f979a1b, "mac80211: simplify idle handling")
     broke ath9k_htc. The reason appears to be that it wants
     to go out of idle before switching channels. To fix it,
     reimplement that sequence.

Johannes, can you please take a look on it.
