[PATCH 08/29] IB/mlx4: Delete an unnecessary check before the function call "kfree" in free_pv_object()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Fri, 17 Feb 2017 22:06:24 +0100

The script "checkpatch.pl" pointed information out like the following.

WARNING: kfree(NULL) is safe and this check is probably not required

Thus fix the affected source code place.
