Despite using M2M in both the decoder and encoder, this driver used vb2_v4l2_buffer as its base buffer structure, and placed a list_head right after the buffer declaration in order to match the layout of a v4l2_m2m_buffer. This is very dangerous as it means the driver will break should the layout of v4l2_m2m_buffer change. Fix this by directly using v4l2_m2m_buffer and updating the sites that accessed the buffer accordingly.
