Running mgag200_driver_unload when the driver init fails early on
causes functions like drm_mode_config_cleanup to be called. The
problem is, drm_mode_config_cleanup crashes because the corresponding
init hasn't happend yet. There really isn't anything to cleanup after
mgag200_device_init, so we can just pass the error code upwards.
