    dbcheck: Abandon dbcheck if we get an error during a transaction
    
    Otherwise, anything that the transaction has already done to the DB will be left in the DB
    even despite the failure.  For example, if a fix wrote to the DB, but then failed a post-write
    check, then the fix will not be unrolled.
    
    This is because we do not have nested transactions in TDB.
