Commit d2add27cf2b8 ("tpm: Add NULL primary creation") introduced
CONFIG_TCG_TPM2_HMAC. When this option is enabled on ppc64 then the
following message appears in the kernel log due to a missing call to
tpm2_sessions_init().
[ 2.654549] tpm tpm0: auth session is not active
Add the missing call to tpm2_session_init() to the ibmvtpm driver to
resolve this issue.
Fixes: d2add27cf2b8 ("tpm: Add NULL primary creation")

Cannot get emails working with my Linux machine given
https://bugzilla.redhat.com/show_bug.cgi?id=2302132
I'll try to sort this out first and then do a pull request.
