Should log table and index name when data inconsistencies occour

[youjiali1995]

Bug Report

TiDB will report and log an error message if it detects data inconsistencies, but it only logs the index name. We don't know the table name! For example,

tidb/executor/distsql.go

Lines 1215 to 1223 in b7c22aa

	logutil.Logger(ctx).Error("inconsistent index handles", zap.String("index", w.idxLookup.index.Name.O),
	zap.Int("index_cnt", handleCnt), zap.Int("table_cnt", len(task.rows)),
	zap.String("missing_handles", fmt.Sprint(GetLackHandles(task.handles, obtainedHandlesMap))),
	zap.String("total_handles", fmt.Sprint(task.handles)))
	// table scan in double read can never has conditions according to convertToIndexScan.
	// if this table scan has no condition, the number of rows it returns must equal to the length of handles.
	return errors.Errorf("inconsistent index %s handle count %d isn't equal to value count %d",
	w.idxLookup.index.Name.O, handleCnt, len(task.rows))

TiDB should log enough information.

@aytrack It's not critical. It's only related to log...

It seems that this issue have been fixed. I will close it.
