media: mtk-jpeg: Remove cancel worker in mtk_jpeg_remove to avoid the crash of multi-core JPEG devices
This patch reverts commitc677d7ae83
("media: mtk-jpeg: Fix use after free bug due to uncanceled work"). The job_timeout_work is initialized only for the single-core JPEG device so it will cause the crash for multi-core JPEG devices. Fix it by removing the cancel_delayed_work_sync function. Fixes:c677d7ae83
