After thinking about this a bit more, let's not keep statistics per-channel
in the HAL.  That's very memory hungry (32k just for channel statistics)
which would be better served by keeping a summary in the ANI state.

Or, later, keep a survey history in net80211.

So:

* Migrate the ah_chansurvey array to be a single entry, for the current
  channel.
* Change the ioctl interface and ANI code to just reference that.
* Clear the ah_chansurvey array during channel reset, both in the AR5212
  and AR5416 reset path.
