x86/entry: Clarify irq_{enter,exit}_rcu()
Because: irq_enter_rcu() includes lockdep_hardirq_enter() irq_exit_rcu() does *NOT* include lockdep_hardirq_exit() Which resulted in two 'stray' lockdep_hardirq_exit() calls in idtentry.h, and me spending a long time trying to find the matching enter calls.
