ipv6: add inet6_rt_del_notify()

Browse source

Move the body of inet6_rt_notify() to __inet6_rt_notify() and give it
the deletion reason. inet6_rt_notify() keeps its prototype, so the
route addition path does not change.

Add inet6_rt_del_notify() and call it from fib6_del_route().
RTA_DEL_REASON now reaches user space on RTM_DELROUTE for routes the
kernel deleted on its own.
