rcu: Remove obsolete comment from __call_rcu()
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beginnings and endings is obsolete.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.
