Rucha Deodhar 9b325e1b7d MDEV-39179: Incorrect NULL handling in UPDATE ... RETURNING result ...

Analysis:
OLD_VALUE() swapped only field->ptr, leaving null_ptr pointing to the
current record. This caused incorrect NULL results.

Fix:
Store null_ptr_old for record[1] and swap it together with ptr to
preserve correct NULL semantics.
