Xiubo Li e016e35846 ceph: fix deadlock or deadcode of misusing dget() ...

[ Upstream commit b493ad718b ]

The lock order is incorrect between denty and its parent, we should
always make sure that the parent get the lock first.

But since this deadcode is never used and the parent dir will always
be set from the callers, let's just remove it.
