Always accept discovered configurations from NDP

Before this change, the NDPDispatcher was allowed to "cancel" the
discovery of default routers/prefixes and auto-generate addresses.
No use case exists for this today so we drop this for now. If a
use case comes up in the future, we should instead invalidate the
discovered configuration through the stack instead of during
discovery.
