Olof Johansson c08f0a92f4 ALSA: echoaudio: simplify get_audio_levels
The loop optimizer seems to go astray here, and produces some warnings
that don't seem valid.

Still, the code can be simplified -- just clear the whole array at the
beginning, and fill in whatever values are valid on the platform.

Warnings before this change (GCC 8.2.0 ARM allmodconfig):
