This patch revert's commit

6c090a11e1c403b727a6a8eff0b97d5fb9e95cb5

since it introduces this problem where we can run orphan cleanup on a volume
that can have orphan entries re-added.  Instead of my original fix, Yan Zheng
pointed out that we can just revert my original fix and then run the orphan
cleanup in open_ctree after we look up the fs_root.  I have tested this with all
the tests that gave me problems and this patch fixes both problems.  Thanks,
