[IPv4] route: Remove unused ifa_anycast field

[IPv4] route: Remove unused ifa_anycast field

[Thomas Graf]

The field was supposed to allow the creation of an anycast route by
assigning an anycast address to an address prefix. It was never
implemented so this field is unused and serves no purpose. Remove it.
