Medium-sized dataset conversion from pandas causes a crash 
Hi ! It looks like an issue with pyarrow, could you try updating pyarrow and try again ? @albertvillanova did you find a solution to this? I´m getting the same problem with some files, @albertvillanova did you find a solution to this?
Hi, I am suffering from the following issue:

## Describe the bug
Conversion to arrow dataset from pandas dataframe of a certain size deterministically causes the following crash:

```
  File "/home/datasets_crash.py", line 7, in <module>
    arrow=datasets.Dataset.from_pandas(d)
  File "/home/.conda/envs/tools/lib/python3.9/site-packages/datasets/arrow_dataset.py", line 783, in from_pandas
    table = InMemoryTable.from_pandas(
  File "/home/.conda/envs/tools/lib/python3.9/site-packages/datasets/table.py", line 379, in from_pandas
    return cls(pa.Table.from_pandas(*args, **kwargs))
  File "pyarrow/table.pxi", line 1487, in pyarrow.lib.Table.from_pandas
  File "pyarrow/table.pxi", line 1532, in pyarrow.lib.Table.from_arrays
  File "pyarrow/table.pxi", line 1181, in pyarrow.lib.Table.validate
  File "pyarrow/error.pxi", line 84, in pyarrow.lib.check_status
pyarrow.lib.ArrowInvalid: Column 1: In chunk 0: Invalid: List child array invalid: Invalid: Struct child array #1 has length smaller than expected for struct array (1192457 < 1192458)
```

## Steps to reproduce the bug
I have a dataset made from replicated single example mocking a dict representation of a publication.
I copy over this example 140k times and create a pandas frame.
I use 'Dataset.from_pandas' and boom

```python
# Sample code to reproduce the bug
import copy
import datasets
import pandas
# serialized dict is quite long to be realistic representation of a publication content
