This is a regression test that tried to make sure that repair correctly clears the XFS inode reflink flag when it detects files that do not share any blocks. However, it does this checking by looking at the (online) lsattr output. This worked fine during development when we exposed the reflink state via the stat ioctls, but that has long since been removed. Now the only way to check is via xfs_db, so switch it to use that.
