### What changes were proposed in this pull request? This PR fixes a correctness bug related to column DEFAULT values in Orc reader. * https://github.com/apache/spark/pull/37280 introduced a performance regression in the Orc reader. * https://github.com/apache/spark/pull/39362 fixed the performance regression, but stopped the column DEFAULT feature from working, causing a temporary correctness regression that we agreed for me to fix later. * This PR restores column DEFAULT functionality for Orc scans and fixes the correctness regression while not reintroducing the performance regression. ### Why are the changes needed? This PR fixes a correctness bug. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? This PR updates a unit test to exercise that the Orc scan functionality is correct. -- This is an automated message from the Apache Git Service.
