[PATCH] drm/vmwgfx: Delete an unnecessary check before the function call "vfree"

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Fri, 22 Jul 2016 13:31:00 +0200

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

This issue was detected by using the Coccinelle software.
