The `mtk_jpeg_set_queue_data` function is now called to set up queue data before signaling a source change through `mtk_jpeg_queue_src_chg_event`. By reorganizing these calls, the patch ensures that necessary queue information is updated prior to transitioning the context state to `MTK_JPEG_SOURCE_CHANGE`. A condition is added to exit early if the context is already in the `MTK_JPEG_SOURCE_CHANGE` state, preventing redundant operations and improving processing efficiency.
