net/mlx4_en: Avoid scheduling restart task if it is already running
Add restarting state flag to avoid scheduling another restart task while
such task is already running. Change task name from watchdog_task to
restart_task to better fit the task role.
Fixes: 1e338db56e5a ("mlx4_en: Fix a race at restart task")
