[PATCH] net/core/skmsg: Delete an unnecessary check before the function call âconsume_skbâ

[Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 22 Aug 2019 18:00:40 +0200

The consume_skb() function performs also input parameter validation.
Thus the test around the call is not needed.

This issue was detected by using the Coccinelle software.
