[PATCH v4, 05/15] media: mtk-vcodec: Call v4l2_m2m_set_dst_buffered() set capture buffer buffered

[Yunfei Dong]

lat thread: output queue      \
                               -> lat hardware -> lat trans buffer
            lat trans buffer  /

core thread: capture queue     \
                                ->core hardware -> capture queue
             lat trans buffer  /

Lat and core work in different thread, setting capture buffer buffered.
