i965: Delete brw_sf_state.c again
"...and stay dead!" Rafael deleted this file inc2b5a26dc2(i965: Convert SF_STATE to genxml.) but Marek accidentally brought it back in commite7a091936f(mesa: replace ctx->Polygon._FrontBit with a helper function) when resolving conflicts. It's not actually even compiled, but it's still here trolling people into thinking it still exists and needs patching.
