2.6.32-stable review patch. If anyone has any objections, please let us know.

------------------

From: Josef Bacik <josef(a)redhat.com>

commit e3acc2a6850efff647f1c5458524eb3a8bcba20a upstream.

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,
