We can't implement ZwLoadDriver() on top of StartService(), since the latter
takes the service database lock. Instead simply move the entire body of
create_driver()/unload_driver() into ZwLoadDriver()/ZwUnloadDriver().
Similarly, clean up the list of loaded drivers in ntoskrnl rather than
winedevice.
