Mingyu Chen cd549d8a8f [improvement](scan) remove concurrency limit if scan has predicate (#13021) ...

If a scan node has predicate, we can not limit the concurrency of scanner.
Because we don't know how much data need to be scan.
If we limit the concurrency, this will cause query to be very slow.

For exmple:
select * from tbl limit 1, the concurrency will be 1;
select * from tbl where k1=1 limit 1, the concurrency will not limit.
