  tpm: Address !chip->auth in tpm_buf_append_hmac_session*() (2024-07-05 02:12:27 +0300)

----------------------------------------------------------------
Hi

Contains the fixes for !chip->auth condition, preventing the breakage
of:

* tpm_ftpm_tee.c
* tpm_i2c_nuvoton.c
* tpm_ibmvtpm.c
* tpm_tis_i2c_cr50.c
* tpm_vtpm_proxy.c

All drivers will continue to work as they did in 6.9, except a single
warning (dev_warn() not WARN()) is printed to klog only to inform that
authenticated sessions are not enabled.

BR, Jarkko
