ceph: fix d_subdirs ordering problem
We misused list_move_tail() to order the dentry in d_subdirs.
This will screw up the d_subdirs order.
This bug can be reliably reproduced by:
1. mount ceph fs.
2. on ceph fs, git clone git://ceph.newdream.net/git/ceph.git
3. Run autogen.sh in ceph directory.
(Note: Errors only occur at the first time you run autogen.sh.)
