tpm: ibmvtpm: Call tpm2_sessions_init() to initialize session support

Browse Source 
Commit d2add27cf2 ("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.
