[PATCH 2/4] GPU-DRM-QXL: Move three assignments in qxl_device_init()

[SF Markus Elfring]

From: Markus Elfring <elfring@xxxxxxxxxxxxxxxxxxxxx>
Date: Wed, 21 Sep 2016 22:33:54 +0200

Move the assignments for three data structure members to the end
so that they will only be performed if the desired resource allocations
succeeded by this function.
