Merge #20868: validation: remove redundant check on pindex

c943282b5e validation: remove redundant check on pindex (jarolrod)

Pull request description:

  This removes a redundant check on `pindex` being a `nullptr`. By the time we get to this step `pindex` is always a `nullptr` as the branch where it has been set would have already returned.

  Closes #19223
