net/sched: act_tunnel_key: Don't dump dst port if it wasn't set
It's possible to set a tunnel without a destination port. However, on dump(), a zero dst port is returned to user space even if it was not set, fix that. Note that so far it wasn't required, b/c key less tunnels were not supported and the UDP tunnels do require destination port.
