[PATCH] GPU-DRM-Exynos: Delete an unnecessary check before the function call "vunmap"

[SF Markus Elfring]

From: Markus Elfring <elfr...@users.sourceforge.net>
Date: Thu, 21 Jul 2016 19:23:25 +0200

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

This issue was detected by using the Coccinelle software.
