[ 25/34] eCryptfs: Remove extra d_delete in ecryptfs_rmdir

[Greg KH]

2.6.32-longterm review patch.  If anyone has any objections, please let me know.

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

From: Tyler Hicks <tyhicks@xxxxxxxxxxxxxxxxxx>

commit 35ffa948b2f7bdf79e488cd496232935d095087a upstream.

vfs_rmdir() already calls d_delete() on the lower dentry. That was being
duplicated in ecryptfs_rmdir() and caused a NULL pointer dereference
when NFSv3 was the lower filesystem.
