Subject: nfs: fix oops in nfs_rename()
From: OGAWA Hirofumi <hirofumi@xxxxxxxxxxxxxxxxxx>
Recent change is missing to update "rehash". With that change, it will
become the cause of adding dentry to hash twice.
This explains the reason of Oops (dereference the freed dentry in
__d_lookup()) on my machine.
