kvm: nVMX: VMWRITE checks unsupported field before read-only field
commit 693e02cc24090c379217138719d9d84e50036b24 upstream.
According to the SDM, VMWRITE checks to see if the secondary source
operand corresponds to an unsupported VMCS field before it checks to
see if the secondary source operand corresponds to a VM-exit
information field and the processor does not support writing to
VM-exit information fields.
