[PATCH] ath5k: Don't wake internal queues

[Bruno Randolf]

We should only wake up queues which mac80211 knows about (queues 0-3). We have
another internal queue ("CAB", queue number 6) which we use for power-saved
frames. When transmitted frames are processed from this queue, we have to make
sure we don't bother mac80211 with waking a queue it doesn't know about.

this fixes:
