upd_plane() upd_land() and left planes and land units lost to lack of maintenance on their carriers. Cargo lists were fine anyway, because unit_cargo_init() ignored dead units. But when the dead unit got reused for building a new one, pln_prewrite() / lnd_prewrite() got confused and attempted to take it off its carrier, which made clink_rem() oops, because the unit wasn't on the cargo list. No real harm done, as oops recovery was fine. Fix upd_plane() and upd_land() to clear the carrier. Make unit_cargo_init() oops when it finds dead units on carriers.
