Accept IPv6 link local address during interface validation

Link local address is a valid address on IPv6 network when we are using
SLAAC instead of DHCPv6, current interface validation bypass link local
address and fails the introspection.
Interfaces without link carrier don't have link local addresses so this
should be fine.
