[RFC 0/1] tcp: constify congestion_ops

This is a proposed method of making TCP congestion_ops structure const.

I wonder if restricting congestion control choices is still necessary?
It seems like being overly paranoid, and better enforced by having a more
limited kernel config, seccomp or other mechanism.
