Tracing events for packets without CIP header have a parameter of data_blocks/data_block_counter, but events for packets with CIP header don't. This is not good to unify these events.
This commit adds the missing parameters to the events. In timing to probe 'in_packet' event, data_blocks and data_block_counter are not calculated yet. This commit also changes the timing.
