`IterableDataset.from_spark` does not support multiple workers in pytorch `Dataloader`
### Describe the bug

Looks like `IterableDataset.from_spark` does not support multiple workers in pytorch `Dataloader` if I'm not missing anything.

Also, returns not consistent error messages, which probably depend on the nondeterministic order of worker executions

Some exampes I've encountered:

```

### Steps to reproduce the bug

```python
import pandas as pd
import numpy as np

batch_size = 16

pdf = pd.DataFrame({
    key: np.random.rand(16*100) for key in ['feature', 'target']
})
test_df = spark.createDataFrame(pdf)

from datasets import IterableDataset
from torch.utils.data import DataLoader

ids = IterableDataset.from_spark(test_df)
for batch in DataLoader(ids, batch_size=16, num_workers=4):
    for k, b in batch.items():
        print(k, b.shape, sep='\t')
    print('\n')
```

### Expected behavior

For `num_workers` equal to 0 or 1 works fine as expected:

```
feature	torch.Size([16])
target	torch.Size([16])


feature	torch.Size([16])
target	torch.Size([16])
....
```

Expected to support workers >1.
