struct trdstr members trd_x, trd_y are used only for teleporting trades. For others, trad() wrote garbage coordinates to the trade file. They weren't used except by xdump. Fortunately, even there they're visible only to deities. Write invalid coordinates instead. Do that in set() as well, so that coordinates are valid only when we have a teleport destination. Spotted by the Clang Static Analyzer.
