Bjoern A. Zeeb 8bda9f9c56 netlink: fix accessing freed memory 
The check for if_addrlen in dump_iface() is not sufficient to determine
if we still have a valid if_addr.  Rather than directly accessing if_addr
check the STAILQ (for the first entry).
This avoids panics when destroying cloned interfaces as experienced with
net80211 wlan ones.
