Add debugging log to see if DHCPv6 client sends Renew/Rebind message.
Based on current implementation, it's possbile for DHCPv6 client to skip
renew/rebind message transmission if there are no renewable prefixes in
the last Reply message. Add debugging log there to confirm if DHCPv6
client has sent Renew/Rebind message or not.
