[PATCH] drm/tegra: Delete an unnecessary check before the function call "vunmap"

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Sat, 16 Jul 2016 07:23:42 +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.
