We had to enable the Negotiate provider a while back so programs that expected 
that provider to be present would be happy. This broke programs that expect a 
Negotiate provider to actually do something if it is present. This fix works 
around that new issue by thunking all calls to Negotiate to NTLM.

That function doesn't exist anymore in Wine.

This will prevent the device from trying to unregister the window again on
release.
