[PATCH] KVM: nVMX: Fix consistency check on injected exception error code

Current versions of Intel's SDM incorrectly state that "bits 31:15 of the VM-Entry exception error-code field" must be zero. In reality, bits 31:16 must be zero, i.e. error codes are 16-bit values. The bogus error code check manifests as an unexpected VM-Entry failure due to an invalid code field
