fix: don't deactivate other batches

[dummdidumm]

There's a possibility of a race condition where batch.deactivate() is called while current_batch !== batch, and so it would deactivate another batch, which can lead to zombie batches that are never flushed, subsequently leading to wrong batch_values. This fixes that by checking if the current batch is the own batch.

Fixes #17109
