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

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Thu, 5 Feb 2015 10:12:51 +0100

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.
