xfs_repair was not detecting that version 3 inodes are invalid for for non-CRC filesystems. The result is specific inode corruptions go undetected and hence aren't repaired if only the version number is out of range. The core of the problem is that the XFS_DINODE_GOOD_VERSION() macro doesn't know that valid inode versions are dependent on a superblock version number. Fix this in libxfs, and propagate the new function out into the rest of xfsprogs to fix the issue.
