executor: Remove useless error logs for indexLoopUp executor when context canceled

[yibin87]

What problem does this PR solve?

Issue Number: close #61072

Problem Summary:
Problem described in #61072

What changed and how does it work?

In this PR, when index/table work failed, we first check if context is cancelled. And only log errors when context is not cancelled. Doesn't use WithCancelCause function to pass cancel cause here, since the actual root cause is limit executor quit quitely, by returning empty data.

Check List

Tests

• Unit test
• Integration test
• Manual test (add detailed scripts or steps below)
  Use tpch, sf=1 benchmark, add index for orders table:
  alter table orders add index(o_orderdate);
  Then execute the following sql and check tidb.log to see if "table reader fetch next chunk failed" log doesn't exists any more:

Hi @yibin87. Thanks for your PR.

PRs from untrusted users cannot be marked as trusted with /ok-to-test in this repo meaning untrusted PR authors can never trigger tests themselves. Collaborators can still trigger tests on the PR using /test all.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes-sigs/prow repository.
