A user reported a WARN_ON() when trying to run btrfsck --repair on his fs with bad key ordering. This was because the root that was broken wasn't part of the transaction yet. We do this open coded thing in a few other places in fsck, so just make it a helper function and make sure all the places that need to call it do call it. With this patch he was able to run repair without it dying.
