IPACM: Fix conntrack event comes earlier than new neighbor

In lan2lan WLAN driver unload/reload scenario, we found
conntrack event comes earlier than new neighbor event.
To handle this we add connection cache in lan2lan module
to cache early-arrived conntrack events. Also fix to
use host to network order.
