These expressions are equivalent since levels is always odd, and
overflow is impossible due to the constraints set by the assert().

4c886d613d Detect byte-swapped AC-3 and support decoding it directly. 
This allows the AC-3 decoder to be used directly with RealMedia
decoders that unlike the libavformat one do not byte-swap automatically.
Since the new code is only used in case we would fail directly otherwise
there should be no risk for regressions.

Depending on error_recognition is not correct, low values do
certainly not mean it is ok to crash.
