From: Dave Chinner <dchinner@xxxxxxxxxx> Source kernel commit: 038ca189c0d2c1570b4d922f25b524007c85cf94 Discovered when trying to track down a weird recovery corruption issue that wasn't detected at recovery time. The specific corruption was a zero extent count field when big extent counts are in use, and it turns out the dinode verifier doesn't detect that specific corruption case, either. So fix it too.
