llvmpipe: Ensure outdated framebuffer state is not reused in lp_setup_bind_framebuffer().
We were starting a scene whenever lp_setup_get_vertex_info() was called by the draw module. So when when all primitives were culled/clipped, not only did we create a new scene for nothing, but we end up using the old scene with the old framebuffer state instead of a new one. Fix consists in: - don't call lp_setup_update_state() in lp_setup_get_vertex_info() -- no longer necessary - always setting the scene state before binning a command -- query commands were bypassing it - assert no old scene is reused in lp_setup_bind_framebuffer()
