Fix T89455: Cycles crash when rendering a Mesh with autosmooth 

The crash was caused by a mistake in 5f9677fe0c
where the pointers to the custom data layers would be overwritten with the one
for the first layer, as CustomData_duplicate_referenced_layer is only about the
first layer. customData_duplicate_referenced_layer_index should be used instead
to duplicate the right layer.
