A virtio_balloon's parent device may be configured so that a configuration change interrupt is a wakeup event. Extend the processing of such a wakeup event until the balloon finishes inflating or deflating by calling pm_stay_awake/pm_relax in the virtio_balloon driver. Note that these calls are no-ops if the parent device doesn't support wakeup events or if the wakeup events are not enabled. This change allows the guest to use system power states such as s2idle without running the risk the virtio_balloon's cooperative memory management becoming unresponsive to the host's requests.
