The lockless write this race needs no longer exists after this and the
following two patches: scx_bpf_task_set_slice() writes p->scx.slice
directly only when the caller holds the task's current rq lock, and every
other caller is routed through the deferred slice_oob path, drained under
the rq lock at the top of update_curr_scx() before the min_t().

Thanks.
