[PATCH v2 1/2] hantro: h264: Get the correct fallback reference buffer

[Ezequiel Garcia <ezequiel@collabora.com>]

If the bitstream and the application are incorrectly configuring
the reference pictures, the hardware will need to fallback
to using some other reference picture.

When the post-processor is enabled, the fallback buffer
should be a shadow buffer (postproc.dec_q), and not a
CAPTURE queue buffer, since the latter is post-processed
and not really the output of the decoder core.

Fixes: 8c2d66b036c77 ("media: hantro: Support color conversion via post-processing")
