adapter_info_so_needed() treats its "opaque" parameter as a S390FLICState,
but the function belongs to a VMStateDescription that is attached to a
TYPE_VIRTIO_CCW_BUS device. This is currently causing a crash when the
user tries to save or migrate the VM state. Fix it by using s390_get_flic()
to get the correct device here instead.
