sched_ext: Use rcu_access_pointer() for the first_task comparison
dsq->first_task is __rcu for the lockless scx_bpf_dsq_peek(). The task
removal path compares it against the departing task with a plain load, which
sparse flags. The comparison runs under the dsq lock and only tests
identity, so rcu_access_pointer() is the fit.
