James's code uses the 'parent' handle from the ASN.1 directly if it
matches 0x81xxxxxx. If it doesn't, then he has a function equivalent to
your init_tpm_primary() function, except that the value used for
in.primaryHandle is the one from the ASN.1. Which seems like it's
designed to allow the user of other hierarchies. It defaults to
RH_OWNER, while yours is hard-coded to that.

But I see James is awake now, so I'll defer to him...
