drm/mgag200: Fix driver_load error handling
mgag200_driver_load's error path just calls the drm driver's
driver_unload op. It isn't safe to call this because it doesn't handle
things well if driver_load fails somewhere mid way.
Replace the call to mgag200_driver_unload with a more finegrained
error handling path.
