KVM: x86: Disable APIC logical map if vCPUs are aliased in logical mode
Disable the optimized APIC logical map if multiple vCPUs are aliased to
the same logical ID. Architecturally, all CPUs whose logical ID matches
the MDA are supposed to receive the interrupt; overwriting existing map
entries can result in missed IPIs.
