net/mlx4_en: Disable HW clock overflow check when no HW support

amirv · davem330 · commit dc8142ea8906 · 2013-04-26T23:29:13.000-04:00
Should not run HW clock overflow check if HW clock is not supported. Also, since
this watchdog is the only customer of service_task, no need to start it in that case.
