ocfs2: Correct merge of 52f7c21b (Move /sys/o2cb to /sys/fs/o2cb)

Commit 52f7c21b was intended to move
/sys/o2cb to /sys/fs/o2cb, providing /sys/o2cb as a symlink for
backwards compatibility.  However, the merge apparently added the
symlink but failed to move the directory, resulting in a duplicate
filename error.  It's a one-line change that was missing.
