Fix bug with Samba not recognising an 6to4 IPv6 interface.

Browse Source 
"The 6to4 interface has the flags IFF_POINTTOPOINT interface but no
ifa_dstaddr as it's not at the IPv6 level a point to point interface
(at least from my understanding), as we don't have a IFF_BROADCAST
flag set (I have the impression that this flag is only set on a
interface that has also an IPv4 address) the first test is not valid
also, which result in a skipped interface."
