GUIFormSpecMenu::OnEvent code style update and small refactor

* Make method (more) consistent with current code stlye
* Move index into loop constructor after @rubenwardy's suggestion
* Cache inv_s->getList(s.listname), which removes a possibly bad scenario
of inv_s being null.
* Properly check for validity
