drm/vmwgfx: reorder framebuffer init sequence
vmwgfx has an oddity, when failing to reference the surface it'll return 0, since that's what the successfull drm_framebuffer_init will leave behind in ret. Fix this up by returning -EINVAL. Split out from all the other driver updates due to the above tiny semantic change. Shouldn't matter though since the reference grabbing seemingly can't fail.
