If structure mtk_jpeg_src_buf wants to be allocated to memory, it needs to be placed vb2_v4l2_buffer at the starting position, because structure vb2_buffer is at the starting position of vb2_v4l2_buffer, and the allocated size is set to the size of structure mtk_jpeg_src_buf, so as to ensure that structures mtk_jpeg_src_buf, vb2_v4l2_buffer and vb2_buffer can all be allocated memory.
