From: Ian Kent <raven@xxxxxxxxxx>
Subject: autofs: remove ino free in autofs4_dir_symlink()
The inode allocation failure case in autofs4_dir_symlink() frees the
autofs dentry info of the dentry without setting ->d_fsdata to NULL.
That could lead to a double free so just get rid of the free and leave it
to ->d_release().
