firewire: fw-sbp2: use device generation, not card generation
There was a small window where a login or reconnect job could use an already updated card generation with an outdated node ID. We have to use the fw_device.generation here, not the fw_card.generation, because the generation must never be newer than the node ID when we emit a transaction. This cannot be guaranteed with fw_card.generation. Furthermore, the target's and initiator's node IDs can be obtained from fw_device and fw_card. Dereferencing their underlying topology objects is not necessary. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Verified in concert with subsequent memory barriers patch to fix 'giving up on config rom' issues on multiple system and drive combinations that were previously affected.
