[CI][C++] Flaky DatasetWriterTestFixture.MaxRowsOneWriteBackpresure test

[mapleFU]

Describe the enhancement requested

As mentioned in #38885 (comment) , the DatasetWriterTestFixture.MaxRowsOneWriteBackpresure might failed. This might because:

1. In CI env, the file operation would be slow, see: GH-38884: [C++] DatasetWriter release rows_in_flight_throttle when allocate writing failed #38885 (comment)
2. Maybe the execution has potential deadlock, see: GH-38884: [C++] DatasetWriter release rows_in_flight_throttle when allocate writing failed #38885 (comment)

I'll ensure if (2) has problem. If not, I'll just make test runs faster ( About (1), The assertion will wait for 64secs, which might be slow)

Component(s)

C++, Continuous Integration

Hello @mapleFU, I would appreciate it if you could clarify this issue for me. Do you consider this issue to be a blocker for next release v15.0.0 or is it possible to skip this test at the moment?

I'll fix it before v15.0.0, it's ok to become a blocker or not :-)

I think (2) can hardly happens, because I didn't see any blocking wait called. Just fixing (1) here.
