Since 260075bde769 ("tcp, udp, fwd: Run all port scanning from a single timer"), CALL_PROTO_HANDLER() is only used for TCP. UDP and ICMP timers now run from flow_defer_handler(), making the timer_run fields in struct udp_ctx and struct icmp_ctx dead stores.
Remove the unused fields, drop struct icmp_ctx entirely (it has no remaining members), and stop initialising them in timer_init().
