    sna: Validate framebuffer tiling before creation
    
    In sna_pixmap_alloc_gpu() a different than the default tiling may be picked
    by a usage hint. Before passing the tiling to kgem_create_2d() fix it up
    by calling kgem_choose_tiling(). This avoids kgem_surface_size() not being a
    to find a surface size for the tiling value.
