MFC 303406,303501: Fix panic when using aio_fsync().

303406:
Adjust tests in fsync job scheduling loop to reduce indentation.

303501:
Fix locking issues with aio_fsync().

- Use correct lock in aio_cancel_sync when dequeueing job.
- Add _locked variants of aio_set/clear_cancel_function and use those
  to avoid lock recursion when adding and removing fsync jobs to the
  per-process sync queue.
- While here, add a basic test for aio_fsync().
