Once the device is closed, we no longer keep track of the link state and
no longer have register access to determine the link state.  So we
assume it is down.  In reality, it may still be up if WoL is enabled or
management firmware is running, but the driver can no longer keep track
of it.  If we have to assume one or the other, I think it is more
correct to assume it is down.
