    if_tun: Disallow to destroy an opened device
    
    When a tun device (created via 'ifconfig') is opened, disallow to destroy
    it (e.g., ifconfig destroy).  Otherwise, a panic occurs when the caller
    closes the device, since it has been already destroyed.
    
    Following the previous fix to if_tap.
