Previously we accepted non-linear buffers for the cursor plane. This results in bad output, DC validation failures and oops. Make sure the FB uses a linear layout in the atomic check function. The GFX8- check is inspired from ac_surface_set_bo_metadata in Mesa. The GFX9+ check comes from convert_tiling_flags_to_modifier.
