[PULL 1/6] virtio-gpu: no point of checking res->iov

[Gerd Hoffmann <kraxel@redhat.com>]

From: Dongwon Kim <dongwon.kim@intel.com>

The code should check the opposite condition of res->iov because it will be null
if virtio_gpu_create_mapping_iov fails and actually this checking is not even
required because checking on ret covers all failing cases.
