[PATCH 2/5] ath9k: return when short FFT frame was handled

[Simon Wunderlich]

With the loop break like this, there are false "FFT report truncated"
messages because the iterator is not advanced as the check expects.

Instead, just return, for a single frame there is nothing left to be
done anyways.
