Can you please explain what this extra test accomplishes?

No need for an extra test here. Just let DM_NO_MECHANISM select
inhibit_delay_req during port initialization.

Please remove this. DM_NO_MECHANISM doesn't make any sense on the
server side. If a node receives a delay request, then it aught to
answer with a reply.
DM_NO_MECHANISM is solely about the client.

Please remove this. We a not adding any more command line options.
