The __call_rcu() comment about opportunistically noting grace period beginnings and endings is obsolete. RCU still does such opportunistic noting, but in __call_rcu_core() rather than __call_rcu(), and there already is an appropriate comment in __call_rcu_core(). This commit therefore removes the obsolete comment.
