[PATCH] kernel-audit: Delete unnecessary checks before two function calls

From: Markus Elfring <elfring(a)users.sourceforge.net&gt; Date: Sun, 15 Nov 2015 12:38:33 +0100 The functions consume_skb() and kfree_skb() test whether their argument is NULL and then return immediately. Thus the tests around their calls are not needed. This issue was detected by using the Coccinelle software.
