avfilter/af_volume: fix precision=fixed and volume=0 case When precision is fixed and volume is 0, filter_frame does not perform any operation on the output buffer. This works if the output buffer has been allocated and zeroed with ff_get_audio_buffer but not if the input buffer is used as output buffer. Fix this by not using the input buffer as output buffer if precision is fixed and volume is 0.
