```

The callback `ListObjectsV2Handler` is being called recursively and the mutex is non-reentrant thus deadlock.

To fix it I got rid of the mutex on `TreeWalker` by using `arrow::util::internal::TaskGroup` instead of manually tracking the #/status of in-flight requests.

Closes apache#9842 from westonpace/bugfix/arrow-12040
