What problem does this PR solve?
Issue Number: close #35638
Problem Summary:
IndexLookupHashJoin hangs when used with limit.
innerWorker of IndexLookupHashJoin is still running when limitExec calls Close(). So no goroutine will read result, which makes the
task.resultCh
be full, and it's stucked when innerWorker try to push result.What is changed and how it works?
