[PATCH tip/core/rcu 2/3] cpu/hotplug: Get rid of CPU_STARTING reference

[Paul E. McKenney]

From: Sebastian Andrzej Siewior <bigeasy@xxxxxxxxxxxxx>

CPU_STARTING is scheduled for removal. There is no use of it in drivers
and just compatibility use core code. This patch removes it from an
RCU-related comment.
