[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. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
