TypeError: 'bool' object is not iterable when filtering a datasets.arrow_dataset.Dataset
### Describe the bug

Hi, 

Thanks for the amazing work on the library!

**Describe the bug**

I think I might have noticed a small bug in the filter method. 
Having loaded a dataset using `load_dataset`,  when I try to filter out empty entries with `batched=True`, I get a TypeError.

### Steps to reproduce the bug

```
train_dataset = train_dataset.filter(
            function=lambda example: example["image"] is not None, 
            batched=True,
            batch_size=10)
```
Error message:

```
File .../lib/python3.9/site-packages/datasets/fingerprint.py:480, in fingerprint_transform.<locals>._fingerprint.<locals>.wrapper(*args, **kwargs)
    476             validate_fingerprint(kwargs[fingerprint_name])
    478 # Call actual function
--> 480 out = func(self, *args, **kwargs)
...
-> 5666 indices_array = [i for i, to_keep in zip(indices, mask) if to_keep]
   5667 if indices_mapping is not None:
   5668     indices_array = pa.array(indices_array, type=pa.uint64())

TypeError: 'bool' object is not iterable
```

**Removing batched=True allows to bypass the issue.** 

### Expected behavior

According to the doc, "[batch_size corresponds to the] number of examples per batch provided to function if batched = True", so we shouldn't need to remove the batchd=True arg?
