[POWERPC] Fix irq radix tree remapping typo 

The code for using the radix tree for reverse mapping of interrupts has
a typo that causes it to create incorrect mappings if the software and
hardware numbers happen to be different. This would, among others, cause
the IDE interrupt to fail on js20's. This fixes it.
