Qian Cai 39916897cd drm/vmwgfx: fix a warning due to missing dma_parms 
Booting up with DMA_API_DEBUG_SG=y generates a warning due to the driver
forgot to set dma_parms appropriately. Set it just after vmw_dma_masks()
in vmw_driver_load().

DMA-API: vmwgfx 0000:00:0f.0: mapping sg segment longer than device
claims to support [len=2097152] [max=65536]
