dix: don't allow disabling XTest devices

Browse Source 
Disabling a XTest device followed by an XTest API call crashes the server.
This could be fixed elsewhere but disabled devices must not send events
anyway. The use-case for disabled XTest devices is somewhat limited, so
simply disallow disabling the devices.
