I did some DTrace debugging and found that ieee80211_ioctl_delkey fails 
with errno=2 (No such file), which is caused by ieee80211_find_vap_node 
returning null. And ieee80211_find_vap_node looks for some MAC address.

I think the problem is that I changed the MAC address of the ath0 
interface, and the old one got cached somewhere.
