ath5k: enable Power-Save Polls by setting the association ID 

mac80211 has long provided us the association ID. This isn't useful except
for Power-Save polling which now gets enabled. We can now poll for our
pending frames on the AP during power save.

You can review the details of Power-Save on the wireless wiki:
