audio: fix channel conversion with NA channels 

The case at hand was 5.1 -> fl-fr-fc-lfe-na-na (apparently triggered by
ALSA). That means only the NA channels have to be cleared, but the
result was actually that fc and lfe were cleared. This is due to a
simple regression in the reorder code, which quite obviously got the
index of the first NA channel wrong.
