x2apic feature is in the kvm_default_props and automatically added to all
CPU models when KVM is enabled. But userspace devices don't support x2apic
which can't be enabled without the in-kernel irqchip. It will trigger
warning of "host doesn't support requested feature: CPUID.01H:ECX.x2apic
[bit 21]" when kernel_irqchip is off. This patch is to fix it via removing
x2apic feature when kernel_irqchip is off.
