Description

This code is currently broken:

https://github.com/apache/arrow/blob/4bbb74713c6883e8523eeeb5ac80a1e1f8521674/csharp/src/Apache.Arrow/Ipc/MessageSerializer.cs#L147

 

We need to use the `childFields` parameter when creating the ListType, that way if there are recursive nested types, like List<Struct>, the correct types get flown down.
