powerpc/irq: Always free duplicate IRQ_LEGACY hosts
Since kmem caches are allocated before init_IRQ as noted in 3af259d155 (powerpc: Radix trees are available before init_IRQ), we now call kmalloc in all cases and can can always call kfree if we are asked to allocate a duplicate or conflicting IRQ_HOST_MAP_LEGACY host.
