Jim Mattson dd2d6042b7 kvm: nVMX: VMWRITE checks VMCS-link pointer before VMCS field 
According to the SDM, a VMWRITE in VMX non-root operation with an
invalid VMCS-link pointer results in VMfailInvalid before the validity
of the VMCS field in the secondary source operand is checked.

For consistency, modify both handle_vmwrite and handle_vmread, even
though there was no problem with the latter.

Fixes: 6d894f498f ("KVM: nVMX: vmread/vmwrite: Use shadow vmcs12 if running L2")
