Review Comment:
Thanks for this fix. Just had a quick followup question though. Should the
nested dict work too? e.g.)
```python
import pyarrow as pa
pa.array([[{'a': 1, 'b': 2}, {'c': 3}]], pa.list_(pa.map_(pa.string(),
pa.int64())))
```
It currently fails w/
```
pyarrow.lib.ArrowTypeError: Could not convert {'a': 1, 'b': 2} with type
dict: was not a sequence or recognized null for conversion to list type
```
