powerpc/64s: Use the HV handler for external IRQ replay in HV mode on POWER9
POWER9 host external interrupts use the h_virt_irq_common handler, so
use that to replay them rather than using the hardware_interrupt_common
handler. Both call do_IRQ, but using the correct handler reduces
i-cache footprint.
