Fix T98253: Gpencil Lineart crashes when undoing creation of linked copy

These lines were not used now because the handling of copy data has changed.

Assigning the `eval` data can produce unexpected result, especially since everywhere ID_RECALC_TRANSFORM is used, we also do a copy on write. That should take care of `ob->data` for the eval object.
