Filter out default address if it's not on the enumerated list.
Filter out default address if it's not on the enumerated list.

Chrome uses dual-stack socket on windows which will cause the generation of IPv4-mapped IPv6 address as the default IPv6 address. This particular address is not in the enumerated list so the end behavior is that we generate a new candidate which is not available even when there is no ip permission check.
