i2c: i801: Avoid potential double call to gpiod_remove_lookup_table
commit ceb013b2 upstream. If registering the platform device fails, the lookup table is removed in the error path. On module removal we would try to remove the lookup table again. Fix this by setting priv->lookup only if registering the platform device was successful. In addition free the memory allocated for the lookup table in the error path.
