    elm_calendar: Do not pass NULL to function.
    
    Summary:
    T7076
    
    legacy calendar inc/dec button has auto repeat feature.
    for that if user click the button very quickly, we delete internal timer 
than it will pass to function.
    
    to prevent this, need to check NULL pointer.
