Subject: [PATCH]: cleanup debug message in init_kstat_irqs()

Cleanup a debug message in init_kstat_irqs().

This debug message can result in valid output like

	alloc kstat_irqs on node -1

which looks alot like an error message.

This debug statement has been in the kernel for over a year, so I think it is
safe to remove it and report the node in only the error case instead.
