[WINSRV] usersrv: Simplify sanity checks in UserClientShutdown

Browse source 
UserClientShutdown will never be called for csrss so we don't need to have a check for that. The existing check was broken and wasn't doing anything anyway.
Handle processing winlogon by doing nothing so that consrv won't be bothered about it.
