References: FATE#326289 FATE#326079 FATE#326049 FATE#322398 FATE#326166

Under VF environment, the ucode would be settled to the visible VRAM,
As it would be pinned to the visible VRAM, it's better to add
contiguous flag,otherwise it need to move gpu address during the pin
process. This movement is not necessary.
