Fix the long-standing trivial warnings in net.c.

Cognitively, so much time has passed that these unused variables would offer little help indicating the roadmap for networking. In any case, I have taken care only to comment rather than remove anything that is more than just a throwaway loop counter.

If this commit inconveniences anyone in any way, please contact me personally and I will make it right.
