Modified Files:
        src/sys/netinet6: nd6_nbr.c

Log Message:
Userland really has no business with NA messages.
However, RFC 4861 6.2.5 only says departing routers
*SHOULD* send RA with lifetime of zero and *MUST*
send all subsequent NA messages if the router flag
unset.

To help userland avoid the expensive process of
parsing NA messages, send RTM_CHANGE without a
lladdr in the gateway.
This is different from the intial RTM_ADD also
without a lladdr in the gateway and RTM_DELETE.
