rcu: Cleanup: balance rcu_irq_enter()/rcu_irq_exit() calls

Currently, rcu_irq_exit() is invoked only for CONFIG_NO_HZ,
while rcu_irq_enter() is invoked unconditionally.  This patch
moves rcu_irq_exit() out from under CONFIG_NO_HZ so that the
calls are balanced.

This patch has no effect on the behavior of the kernel because
both rcu_irq_enter() and rcu_irq_exit() are empty for
!CONFIG_NO_HZ, but the code is easier to understand if the calls
are obviously balanced in all cases.
