If raid1_set_limits() fails, the previously\nregistered thread is not unregistered, resulting in a memory leak\nof the md_thread structure and the thread resource itself.\n\nAdd md_unregister_thread() to the error path to properly cleanup\nthe thread, which aligns with the error handling logic of other paths\nin this function.\n\nCompile tested only.
