kvm: vmx: Introduce lapic_mode enumeration
The local APIC can be in one of three modes: disabled, xAPIC or x2APIC. (A fourth mode, "invalid," is included for completeness.) Using the new enumeration can make some of the APIC mode logic easier to read. In kvm_set_apic_base, for instance, it is clear that one cannot transition directly from x2APIC mode to xAPIC mode or directly from APIC disabled to x2APIC mode.
