[patch 5/8] x86/ioapic: Use apic_ack_irq()

[Thomas Gleixner]

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
