Fix MERGE command tag for cross-partition updates.
This ensures that the row count in the command tag for a MERGE is
correctly computed. Previously, if MERGE updated a partitioned table,
the row count would be incorrect if any row was moved to a different
partition, since such updates were counted twice.
Back-patch to v15, where MERGE was introduced.
