Subject: [PATCH] Fix call to unsafeResize in StructColumnReader (#7461)

Summary:
Pull Request resolved: https://github.com/facebookincubator/velox/pull/7461

Ensure call to unsafeResize sets new rows to false in StructColumnReader.
When adding unsafeRowApi (D50577808) I missed setting one call to false instead of the default true.
