[PATCH] s390/ctcm: Delete unnecessary checks before the macro call “dev_kfree_skb”

[Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Thu, 22 Aug 2019 10:55:33 +0200

The dev_kfree_skb() function performs also input parameter validation.
Thus the test around the shown calls is not needed.

This issue was detected by using the Coccinelle software.
