Print the last non-wakeup interrupt received during suspend.  Note that
this may print an (MSI) interrupt that sneaks in just before we actually
enter the idle loop on the primary CPU.  While such an interrupt shouldn't
happen, they won't prevent the machine from reaching a low power idle state.
So at this point these non-wakeup interrupts only need to be investigated
when the primary CPU gets woken up repeatedly.
