net: ipv4: fix infinite loop on secondary addr promotion
secondary address promotion causes infinite loop -- it arranges
for ifa->ifa_next to point back to itself.
Problem is that 'prev_prom' and 'last_prim' might point at the same entry,
so 'last_sec' pointer must be obtained after prev_prom->next update.
