  Log Message:
  -----------
  replication: Avoid theoretical use-after-free error in reset_database().

Code that calls ovsdb_txn_row_delete() should avoid referencing the
deleted row again, because it might be freed.  In practice this shouldn't
really happen in this case because of the particular circumstances, but it
costs little to be careful.
