    [IPV6]: Call inet6addr_chain notifiers on link down
    
    Currently if the link is brought down via ip link or ifconfig down,
    the inet6addr_chain notifiers are not called even though all
    the addresses are removed from the interface.  This caused SCTP
    to add duplicate addresses to it's list.
