MFC r332555: loader: provide values in help_getnext()
With r328289 we attempt to make sure we free the resources allocated in
help_getnext(), however, it is possible that we get no resources allocated
and help_getnext() will return early.
Make sure we have pointers set to NULL early in help_getnext().
