KVM: ia64: destroy ioapic device if fail to setup default irq routing

Browse source 
If KVM_CREATE_IRQCHIP fail due to kvm_setup_default_irq_routing(),
ioapic device is not destroyed and kvm->arch.vioapic is not set to
NULL, this may cause KVM_GET_IRQCHIP and KVM_SET_IRQCHIP access to
unexcepted memory.
