    wifi: Disable periodic scan only when Wi-Fi is disabled
    
    The periodic Wi-Fi scan is introduced in 84279c4a. It's designed to
    scan the Wi-Fi list every 15 seconds and disable the scan when Wi-Fi is
    disabled.
    
    But currently the periodic check is disabled every time
    wireless_enabled_toggled() is called, which is wrong. Because it can
    mean Wi-Fi is enabled or disabled.
    
    Fix that by disabling periodic scan only when Wi-Fi is disabled.
    
    fixes 84279c4a
