nat: fix static mapping segv

Browse Source 
Adding a nat44 static mapping during startup on a DHCP interface leads
to a segv via this path:
- dhcp_client_acquire_address
- ip4_add_del_interface_address
- ip4_add_del_interface_address_internal
- nat44_ed_add_del_interface_address_cb
- nat44_ed_add_static_mapping
- ip4_interface_first_address

Type: fix
