KVM: nVMX: Set LDTR to its architecturally defined value on nested VM-Exit
Set L1's LDTR on VM-Exit per the Intel SDM: The host-state area does not contain a selector field for LDTR. LDTR is established as follows on all VM exits: the selector is cleared to 0000H, the segment is marked unusable and is otherwise undefined (although the base address is always canonical). This is likely a benign bug since the LDTR is unusable, as it means the L1 VMM is conditioned to reload its LDTR in order to function properly on bare metal.
