KVM: nVMX: Check HOST_IA32_PERF_GLOBAL_CTRL on VM-Entry
Add a consistency check on nested vm-entry for host's
IA32_PERF_GLOBAL_CTRL from vmcs12. Per Intel's SDM Vol 3 26.2.2:
If the "load IA32_PERF_GLOBAL_CTRL"
VM-exit control is 1, bits reserved in the IA32_PERF_GLOBAL_CTRL
MSR must be 0 in the field for that register"
