Commit 6b5d,.. breaks ath5k in WPA-enabled networks

Commit 6b5d,.. breaks ath5k in WPA-enabled networks

[Peter Chubb]

With Linus's current head-of-tree my ath5k cannot associate with
WPA-enabled access points.  I bisected back to this patch:

	    Since commit 6b5d117eddc09cd976ad8030d715f4350f598a22 
	    ath5k: clean up queue manipulation

I suspect at least one of the two wake-up calls that were removed is
actually necessary.

Reverting the patch restores correct behaviour.

Yeah, big oops. :\

So what do we do now?  I guess we should just revert it for now rather
than taking the half that works plus Bruno's fix?

Bruno's patch on top of current head-of-tree works fine.

I hope that not only WPA association is corrupted. I have already 
reported association failures for plain connections.

I have tested to revert this patch, but I did not observe any effect.

There must be something wrong somewhere else.
