*: Fix select lock option for union statement ( #6579 )
...
If for update appears after order by or limit in union, then it is ignored.
If there is no order by or limit, it affects only the near select statement.
This locks both statements.
```
select * from t for update union select * from s for update;
```
This is syntax error:
```
(select * from t) union all (select * from s) for update;
```

store/tikv: fix a potential goroutine leak problem in copIterator ( #6140 )
...
copIterator.Close() closes finished channel and wait for worker goroutines to
exit, worker goroutine send response to channel but nobody receive from the
channel (copIterator already closed), so those goroutine leak and Close() function
hang forever.
Change the worker goroutine to check both response channel and finished channel.
