The 'off' variable in that scope refers to object size to copy.
I did not change it because it's not related to proposed change.

RTE flow library functions cannot work with PMD private items & actions (elements)
because RTE flow has no API to query PMD flow object size . In the patch,
PMD flow elements use object pointer. RTE flow library functions handle PMD element object size
as size of a pointer. PMD handles its objects internally.
