This reverts commit 26524e35.

If we want the T.140 codec to have the AV_CODEC_ID_TEXT codec id,
its type needs to be AVMEDIA_TYPE_SUBTITLE, so, keep interpreting
the text media type as AVMEDIA_TYPE_SUBTITLE.

This makes more sense than mapping to AV_CODEC_ID_SUBRIP. Nothing
indicates that a T.140 track contains subrip sub-titles.

The code has undefined behavior and makes no difference when optimizations
are enabled.

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.
