This happens when starting pluto without having run ipsec _stackmanager.

*kernel_ops->async_fdp is NULL and pluto_event_new() does not like it.

On a separate note, I do not think we should auto-detect "no_kernel". We
should only allow it when explicitely selected. Then this error would
also be a more simple "no kernel stack found".
