kvm: ioapic: Lazy update IOAPIC EOI In-kernel IOAPIC does not receive EOI with AMD SVM AVIC since the processor accelerate write to APIC EOI register and does not trap if the interrupt is edge-triggered. Workaround this by lazy check for pending APIC EOI at the time when setting new IOPIC irq, and update IOAPIC EOI if no pending APIC EOI.
