Martin Karsten 8a6de2627f eventpoll: Control irq suspension for prefer_busy_poll 
When events are reported to userland and prefer_busy_poll is set, irqs
are temporarily suspended using napi_suspend_irqs.

If no events are found and ep_poll would go to sleep, irq suspension is
cancelled using napi_resume_irqs.
