Peter Zijlstra a01353cf18 cpuidle: Fix ct_idle_*() usage
The whole disable-RCU, enable-IRQS dance is very intricate since
changing IRQ state is traced, which depends on RCU.

Add two helpers for the cpuidle case that mirror the entry code:

  ct_cpuidle_enter()
  ct_cpuidle_exit()

And fix all the cases where the enter/exit dance was buggy.
