x86/ioapic: Use apic_ack_irq()
commit 2b04e46d8d0b9b7ac08ded672e3eab823f01d77a upstream.
To address the EBUSY fail of interrupt affinity settings in case that the
previous setting has not been cleaned up yet, use the new apic_ack_irq()
function instead of directly invoking ack_APIC_irq().
Preparatory change for the real fix
