Function blk_ioprio_init only alloc blkg_policy_data which will be freed in blkg_destroy_all, so no blk_ioprio_exit is called when blk_throtl_init is failed in blkcg_init_queue. Also blk_ioprio_exit is not called in blkcg_exit_queue for the same reason. Just remove blk_ioprio_exit to keep behavior consistent.
