powerpc/64s: Prevent fallthrough to hash TLB flush when using radix

In the fix reconnecting hash__tlb_flush() to tlb_flush() the void return on radix__tlb_flush() was not restored and subsequently falls through to the restored hash__tlb_flush(). Guard hash__tlb_flush() under an else to prevent this.
