firewire: fw-ohci: check for misconfigured bus (phyID == 63)
Check NodeID.nodeNumber as per OHCI 1.1 clause 7.2.3.2. See also IEEE 1394a table 5B-1. Also, demote the "node ID not valid" message from error to notification as it is not an error condition. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
