[PATCH][ Xenial] UBUNTU: Fix CVE-2015-1350 regression

[Tim Gardner]

CVE-2015-1350

Commit b3ce51efc535125aa3bea570467ebe7535975467 ('fuse: Propagate dentry down to inode_change_ok()')
introduced a regression in fs/fuse/dir.c where fuse_do_setattr() was being
called with a pointer to an inode structure instead of  a pointer to a dentry structure.
How did this even compile ?
