x86, intr-remap: fix ack for interrupt remapping
Shouldn't call ack_apic_edge() in ir_ack_apic_edge(), because ack_apic_edge() does more than just ack: it also does irq migration in the non-interrupt-remapping case. But there is no such need for interrupt-remapping case, as irq migration is done in the process context. Similarly, ir_ack_apic_level() shouldn't call ack_apic_level, and instead should do the local cpu's EOI + directed EOI to the io-apic. ack_x2APIC_irq() is not neccessary, because ack_APIC_irq() will use MSR write for x2apic, and uncached write for non-x2apic.
