Lorenzo Bianconi a2d481b326 ipv6: send netlink notifications for manually configured addresses
Send a netlink notification when userspace adds a manually configured
address if DAD is enabled and optimistic flag isn't set.
Moreover send RTM_DELADDR notifications for tentative addresses.

Some userspace applications (e.g. NetworkManager) are interested in
addr netlink events albeit the address is still in tentative state,
however events are not sent if DAD process is not completed.
If the address is added and immediately removed userspace listeners
are not notified. This behaviour can be easily reproduced by using
veth interfaces:

$ ip -b - <<EOF
> link add dev vm1 type veth peer name vm2
> link set dev vm1 up
> link set dev vm2 up
> addr add 2001:db8:a🅱️1:2:3:4/64 dev vm1
> addr del 2001:db8:a🅱️1:2:3:4/64 dev vm1
EOF

This patch reverts the behaviour introduced by the commit f784ad3d79
("ipv6: do not send RTM_DELADDR for tentative addresses")
