Yup.

So what's happening (now that I have 30 seconds of spare time):

* the initial reset path in the HAL starts an NF calibration;
* then the driver _immediately_ calls the HAL calibration routine,
which checks if an NF cal is in progress;
* .. and since the previously started one may still be in progress, it
skips (re)starting a new one.

It only shows up on:

* AR5416, in moderately noisy environments;
* any of the chips, if there's a very strong interferer signal present;
* in station mode with scanning, as there's lots of channel changes going on.

The print is there because I'd like to be told if it's constantly
happening. It coincides with strong interference and/or RX deafness,
so it's good to have as a data point.

Thanks again for testing this out!
