    pluto: do not try to send out packets if interface vanished.
    
    I brought up my VPN that gave me an address using XAUTH. This ip got
    configured on my interface (eg wlan0). I brought my tunnel down which
    did not remove the IP address. Now this IP address was being used for
    all my traffic, so I was dead in the water. I tried to --replace and
    --up and this used my old IP. So I manually removed it using ip addr
    del XXXX/32 dev wlan0. Then a retransmit must have hit pluto:
    
    Program received signal SIGSEGV, Segmentation fault.
