userfaultfd/selftests: always dump something in modes
Patch series "userfaultfd: selftests: Small fixes". Some very trivial fixes that I kept locally to userfaultfd selftest program. This patch (of 3): BOUNCE_POLL is a special bit that if cleared it means "READ" instead. Dump that too otherwise we'll see tests with empty modes.
