net: ipv6: send unsolicited NA after DAD

Browse source

[ Upstream commit c76fe2d98c ]

Unsolicited IPv6 neighbor advertisements should be sent after DAD
completes. Update ndisc_send_unsol_na to skip tentative, non-optimistic
addresses and have those sent by addrconf_dad_completed after DAD.

Fixes: 4a6e3c5def ("net: ipv6: send unsolicited NA on admin up")
