- Commit 08e98f6f30 utilises CONFIG_LWIP_ND6_SUPPORT_STATIC_ENTRIES
for adding static entries.
- It moves netif calls that generate GOT IPv6 to NAN_STARTED default
handler without guard, but guards the removal in NDP Confirm handler
- Fix the possible duplicate calls by putting calls from NAN_STARTED
handler under CONFIG_LWIP_ND6_SUPPORT_STATIC_ENTRIES guard
