KVM: x86: Fix invalid secondary exec controls in vmx_cpuid_update()
The commit [ad756a16: KVM: VMX: Implement PCID/INVPCID for guests with
EPT] introduced the unconditional access to SECONDARY_VM_EXEC_CONTROL,
and this triggers kernel warnings like below on old CPUs:
vmwrite error: reg 401e value a0568000 (err 12)
Pid: 13649, comm: qemu-kvm Not tainted 3.7.0-rc4-test2+ #154

This patch adds a check for the availability of secondary exec
control to avoid these warnings.
