We want to use interface_type, not vtn_var->type. They're normally
equivalent, but for geometry/tessellation per-vertex interface arrays,
we need to unwrap a level.
Otherwise, we tried to iterate a structure members but instead used
an array length. If the array length was longer than the number of
fields in the structure, we'd crash.
