    Avoid full_sync in l3_agent for router updates

    While processing a router update in _process_router_update method,
    if an exception occurs, we try to do a full_sync.

    We only need to re-sync the router whose update failed.

    Addressed a TODO in the same method, which falls in similar lines.
