Previosly output was almost useless because background noise, due to
windowing function picked and which is not actually present in audio,
had too much brightness.
Now output of sine wave matches more with SoX.

avfilter/all: propagate errors of functions from avfilter/formats
...
Many of the functions from avfilter/formats can return errors, usually AVERROR(ENOMEM).
This propagates the return values.
All of these were found by using av_warn_unused_result, demonstrating its utility.
Tested with FATE. I am least sure of the changes to avfilter/filtergraph,
since I don't know what/how reduce_format is intended to behave and how it should
react to errors.
Fixes: CID 1325680, 1325679, 1325678.
