using DownloadManager to download from local filesystem and disable_progress_bar, there will be an exception

Describe the bug

i'm using datasets.download.download_manager.DownloadManager to download files like "file:///a/b/c.txt", and i disable_progress_bar() to disable bar. there will be an exception as follows:

AttributeError: 'function' object has no attribute 'close' Exception ignored in: <function TqdmCallback.__del__ at 0x7fa8683d84c0> Traceback (most recent call last): File "/home/protoss.gao/.local/lib/python3.9/site-packages/fsspec/callbacks.py", line 233, in __del__ self.tqdm.close()

i check your source code in datasets/utils/file_utils.py:348 you define TqdmCallback derive from fsspec.callbacks.TqdmCallback

but in the newest fsspec code https://github.com/fsspec/filesystem_spec/blob/master/fsspec/callbacks.py , line 146, in this case, _DEFAULT_CALLBACK will take effect, but in line 234, it calls "close()" function which _DEFAULT_CALLBACK don't have such thing.

so i think the class "TqdmCallback" in datasets/utils/file_utils.py may override "del" function or report this bug to fsspec.

Steps to reproduce the bug

as i said

Expected behavior

no exception
