firewire: fw-ohci: extend logging of bus generations and node ID
Extend the logging of "AR evt_bus_reset, link internal" to "AR evt_bus_reset, generation ${selfIDGeneration}". That way we can check whether this generation matches the one seen in self ID complete event logging. See OHCI 1.1 clause 8.4.2.3. Also extend logging of "firewire_ohci: * selfIDs, generation *" by "local node ID ffc*" in self ID logging to make the local node in AT/AR event logs more obvious.
