If for some reason SIOCAIFADDR fails, exit instead of hanging.
Without this diff I need to kill dhclient(8) with ctrl+C during boot
if I happen to have the address offered by the server configured on
a different interface.
WARNING: do not try to do that on -current without my rt_delete diffs
or your kernel with panic!
Ok?
