ocpp: sh->uid what is the purpose of that field?

[Szewcson]

I'm investigating ocpp implementation and found it somwhat confusing. If this is some kind of uid why it takes value of 0/error code? Is this then used somwhere? If this is not used maybe it should be removed to make code simpler to read? Or maybe this is a placeholder for something? I think in that case there should be a comment about it.

@Szewcson Thanks again for pointing out. sh->uid is outdated code from initial design which has missed on cleanup. I have raised a PR #99820, please review.
