drm/virtio: Set segment size for virtio_gpu device
commit 9c64e749cebd9c2d3d55261530a98bcccb83b950 upstream.
Set the segment size of the virtio_gpu device to the value
used by the drm helpers when allocating sg lists to fix the
following complaint from DMA_API debug code:
DMA-API: virtio-pci 0000:07:00.0: mapping sg segment longer than
device claims to support [len=262144] [max=65536]
