[PATCH tip/core/rcu 3/7] rcu: Remove comment referring to __stop_machine()

[Paul E. McKenney]

From: "Srivatsa S. Bhat" <srivatsa.bhat@xxxxxxxxxxxxxxxxxx>

Although it used to be that CPU_DYING notifiers executed on the outgoing
CPU with interrupts disabled and with all other CPUs spinning, this is
no longer the case.  This commit therefore removes this obsolete comment.
