When interrupt remapping hardware is not in X2APIC, CPU X2APIC mode will be disabled if: 1) Maximum CPU APIC ID is bigger than 255 2) hypervisior doesn't support x2apic mode. But we should only check whether hypervisor supports X2APIC mode when hypervisor(CONFIG_HYPERVISOR_GUEST) is enabled, otherwise X2APIC will always be disabled when CONFIG_HYPERVISOR_GUEST is disabled and IR doesn't work in X2APIC mode.
