KVM: x86: preserve x2APIC LDR on INIT
Logical x2APIC stops working if we rewrite it with zeros.
The best references are SDM April 2015: 10.12.10.1 Logical Destination
Mode in x2APIC Mode
[...], the LDR are initialized by hardware based on the value of
x2APIC ID upon x2APIC state transitions.
and SDM April 2015: 10.12.10.2 Deriving Logical x2APIC ID from the Local
x2APIC ID
The LDR initialization occurs whenever the x2APIC mode is enabled
