Signed-off-by: gengliqi gengliqiii@gmail.com

What problem does this PR solve?

Issue Number: close #5356

Problem Summary:
See #5356.

What is changed and how it works?

See #5356 (comment).
Although the panic doesn't happen by lucky coincidence due to #5274, this PR is still needed for previous branches.
It's easier to pick this PR to other branches than #5274.

The ParallelAggregatingBlockInputStream should be canceled when its processors meet an exception.
Otherwise, the aggregation of non-joined data will still process which leads to panic like #5356 shows.
