The duplication with sctp_setsockopt_nodelay() is quite silly/bad.
Also, why have the 'true' hardcoded? It's what dlm uses, yes, but the
API could be a bit more complete than that.

The APIs are being designed based upon what in-tree users actually
make use of.  We can expand things later if necessary.

`h`	back out one level
