virtio: support irqfd in virtio_notify_config()
virtio_error() calls virtio_notify_config() to inject a VIRTIO
Configuration Change Notification. This doesn't work from IOThreads
because the BQL is not held and the interrupt code path requires the
BQL.
Follow the same approach as virtio_notify() and use ->config_notifier
(an irqfd) when called from the IOThread.
