x86/platform/uv: Use apic_ack_irq()
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 the special uv_ack_apic() implementation which is
merily a wrapper around ack_APIC_irq().
Preparatory change for the real fix
