[PATCH 7/8] sandbox: tpm: Fix TPM2_CC_NV_DEFINE_SPACE command

From: Sean Edmond <seanedmond@microsoft.com>

The TPM 2.0 command reference shows "auth" (type TPM2B_AUTH) before
"publicInfo" (type TPM2B_NV_PUBLIC).

The TPM v2 driver was updated to add this field. The sandbox driver
needs to be updated to match the driver implementation.
