[ 22/82] NFS: kmalloc() doesnt return an ERR_PTR()

[Greg KH]

3.4-stable review patch.  If anyone has any objections, please let me know.

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

From: Dan Carpenter <dan.carpenter@xxxxxxxxxx>

commit 5abc03cd919535c61b813f2319cb38326a41e810 upstream.

Obviously we should check for NULL here instead of IS_ERR().
