Currently, default values of kickfd and callfd are -1. If the values are -1, current code guesses kickfd and callfd haven't been initialized yet. Then vhost library will guess the virtqueue isn't ready for processing. But callfd and kickfd will be set as -1 when "--enable-kvm" isn't specified in QEMU command line. It means we cannot treat -1 as uninitialized state. The patch defines -1 and -2 as VIRTIO_INVALID_EVENTFD and VIRTIO_UNINITIALIZED_EVENTFD, and uses VIRTIO_UNINITIALIZED_EVENTFD for the default values of kickfd and callfd.
