[Python] to_pandas fails if a record batch's length is smaller than the length of its arrays

### Describe the bug, including details regarding any error messages, version, and platform.

It's possible to construct a record batch whose length is smaller than its child arrays. I'm not entirely sure if this is legal (I will ask on the ML). However, if it is, then to_pandas is not working correctly in this situation:

```
# Create a struct array of length 5 with one child of length 5
foo = pa.StructArray.from_arrays([pa.array([1, 2, 3, 4, 5])], names=["x"])
# Creates a struct array of length 2 with one child of length 5
bar = foo.slice(0, 2)
# Creates a record batch of length 2 with one child of length 5
baz = pa.RecordBatch.from_struct_array(bar)
baz.to_pandas()
# Traceback (most recent call last):

```

### Component(s)

Python

Start with python/pyarrow/pandas_compat.py, especially table_to_blockmanager, and reproduce the issue using the RecordBatch snippet in the report. Check how the child array shape reaches pandas when the batch length is smaller; done means baz.to_pandas() completes and returns the expected two-row result.
