These changes break the build for non-Linux hosts. Please introduce a
CONFIG_VHOST_SCSI and #ifdef appropriate sections in hw/virtio-pci.c.
CONFIG_VIRTFS does the same thing.

This flag makes QEMU's virtqueue handling use ioeventfd. Since the
vhost-scsi.c takes over the guest/host notifiers, we never do QEMU
virtqueue processing and the "ioeventfd" flag has no real meaning. You
can drop it.
