device: skip DNS resolution for tentative IPv6 addresses

Browse source 
A tentative IPv6 address can still fail DAD, so don't use it to
resolve the hostname via DNS. Furthermore, tentative addresses can't
be used to contact the nameserver and so the resolution will fail if
there is no other valid IPv6 address. Wait that the address becomes
non-tentative.
