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.
