If there are no IP addresses, ul_netaddrq_bestaddr() returns threshold
ULNETLINK_RATING_BAD, but there were no addresses in the best array, and
best_ifaceq remains unset, which caused crash. Setting the initial
threshold to __ULNETLINK_RATING_MAX and checking for that value fixes that.
And more, it also allows to accept IP addresses with ULNETLINK_RATING_BAD
rating.
