Received packet buffer is not getting freed after processing incoming message in IOS app

chip::System::PacketBuffer::Free(message);

The call to chip::System::PacketBuffer::Free(message); is being made after the PacketBuffer * message has already traversed the buffer list, and therefore message is already set to NULL when calling Free().
