[PATCH] net-hsr: Delete unnecessary checks before the function call "kfree_skb"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 14 Nov 2015 22:23:48 +0100

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

This issue was detected by using the Coccinelle software.
