firewire: ohci: remove obsolete debug logging for IRQ events

Browse Source 
A commit 0d8914165d ("firewire: ohci: add tracepoints event for hardIRQ
event") added "firewire_ohci:irqs" event in v6.11, which can provide
equivalent information to the existing debug logging.

This commit removes the logging.
