[PATCH 1/2] vfio: powerpc/spapr: Delete an unnecessary check before the function call "kfree"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sun, 28 Jun 2015 17:43:48 +0200

The kfree() function tests whether its argument is NULL and then
returns immediately. Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
