Subject: [PATCH] net: bcmgenet: Use BUG_ON instead of if condition followed by BUG

From: "Gustavo A. R. Silva" <[email-masked]>
Date: Thu, 26 Oct 2017 07:16:01 -0500

Use BUG_ON instead of if condition followed by BUG.

Something to notice in this particular case is that unlikely()
is already being called inside BUG_ON macro.

This issue was detected with the help of Coccinelle.
