junyulai a1493a52d0 Fix addRoute replace default route unexpectedly ...

In aosp/1203789, if two routes are with the same destination,
it will be replaced instead of added when calling addRoute.
This breaks scenarios which rely on the ability to add multiple
default routes, such as multiple IPv6 default routes learned
via address autoconfiguration.

This change treats the route is an update if the destination
and nexthop are the same, but different in other properties.
