$NetBSD: patch-gtk_gtklabel.c,v 1.2 2020/07/23 09:09:48 maya Exp $

Don't deref label before we check if it's (among other things)
non-NULL.

Fixes crash with glade, reproduce with:
1. New project
2. Toplevel -> GtkAssistant
3. Press assistant anywhere

Note: this patch was rejected on GTK upstream and glade was patched
to avoid this crash. Will become unnecessary once gtk3 or glade are
updated.
