Disabling the hotplug IRQ is a two-step process. First, inside the IRQ
handler we mark the rogue hotplug pin for disabling. Then later in the
hotplug worker, we actually disable the hotplug pin. So we should not
WARN about the rogue hotplug IRQ being sent until after we have
completed disabling the pin.
