[PATCH] drm/bochs: Delete an unnecessary check before drm_gem_object_unreference_unlocked()

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 15 Jul 2016 14:23:15 +0200

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

This issue was detected by using the Coccinelle software.
