Jarkko Sakkinen 7ca110f267 tpm: Address !chip->auth in tpm_buf_append_hmac_session*() 
Unless tpm_chip_bootstrap() was called by the driver, !chip->auth can
cause a null derefence in tpm_buf_hmac_session*().  Thus, address
!chip->auth in tpm_buf_hmac_session*() and remove the fallback
implementation for !TCG_TPM2_HMAC.
