3.16.42-rc1 review patch.  If anyone has any objections, please let me know.

From: Dan Carpenter <dan.carpenter@...cle.com>

commit 578620f451f836389424833f1454eeeb2ffc9e9f upstream.

We should set the error code if kzalloc() fails.

Fixes: 67cf5b09a46f ("ext4: add the basic function for inline data support")
