[FFmpeg-devel] [PATCH v2 8/8] doc/encoders: Fix libkvazaar documentation

The -threads option is ignored with libkvazaar since it does not have
any of the AV_CODEC_CAP_{FRAME,SLICE,AUTO}_THREADS capabilities. This
commit removes the incorrect documentation as well as the no-op of
setting the number of threads in libkvazaar encoder.

Signed-off-by: Arttu Ylä-Outinen <arttu.yla-outinen at tut.fi>
v2: Rewrite the commit message to communicate why the parameter did not
    work and that the patch also touches libkvazaar.c.
