Fix mishandling of whole-row Vars referencing a view or sub-select.
If such a Var appeared within a nested sub-select, we failed to translate it
correctly during pullup of the view, because the recursive call to
replace_rte_variables_mutator was looking for the wrong sublevels_up value.
Bug was introduced during the addition of the PlaceHolderVar mechanism.
Per bug #5514 from Marcos Castedo.
