dbus: Suppress to show NULL string

wpa_s->dbus_groupobj_path is always NULL so suppress to show it.
This was found by gcc 9.2.1 warning.

dbus/dbus_new.c: In function ‘wpas_dbus_unregister_p2p_group’:
dbus/dbus_new.c:4793:3: warning: ‘%s’ directive argument is null [-Wformat-overflow=]
 4793 |   wpa_printf(MSG_DEBUG,
      |   ^~~~~~~~~~~~~~~~~~~~~
 4794 |       "%s: Group object '%s' already unregistered",
      |       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 4795 |       __func__, wpa_s->dbus_groupobj_path);
      |       ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
