device: check nm_ip6_config_get_address_first_nontentative() argument

Browse source 
Since commit 9ff161b2a1 ("device: move have_ip6_address() to
nm_ip6_config_get_address_first_nontentative()") the IP configuration
argument of nm_ip6_config_get_address_first_nontentative() must be
non-NULL. Add checks where needed.
