#7896 accidentally added a new df = table.to_pandas(..) call without removing the existing one, duplicating the conversion.

Thanks! I'm surprised this didn't blow up before due to the self destruct 🤔

Hmm, that's indeed a good point. With a tiny example, I directly get a segfault calling this twice:

In [1]: table = pa.table({"a": [0,2,3]})

In [2]: df = table.to_pandas(self_destruct=True)

In [3]: df = table.to_pandas(self_destruct=True)
Segmentation fault (core dumped)

Not sure why that doesn't happen in the test suite (or in practice people using this)
