smbd/winbindd: Do an early check if ctdbd is functional
This will avoid panic calls when smbd and winbind is started in cluster mode before ctdb is functional. It still logs something sane at debug level 0, but it does not panic and core anymore. Signed-off-by: Volker Lendecke <vl@samba.org> Reviewed-by: Michael Adam <obnox@samba.org>
