Description

1. Background:
   Left over cleanups suggested by from @sunchao on https://github.com/apache/arrow/pull/9425

Broken out from https://github.com/apache/arrow/pull/9508

1. Rationale:

Rationale: don't use panic! directly (though the caller of this function still calls `unwrap()` so I am not sure how much of an improvement this change really is. However it sets us up for a more `safe` future eventually
