rcu: Fix RCU's NMI documentation
It has long been the case that the architecture must call nmi_enter() and nmi_exit() rather than irq_enter() and irq_exit() in order to permit RCU read-side critical sections in NMIs. Catch the documentation up with reality. Signed-off-by: Paul E. McKenney <paulmck@linux.vnet.ibm.com> Acked-by: Mathieu Desnoyers <mathieu.desnoyers@efficios.com>
