tpm: Use auth only after NULL check in tpm_buf_check_hmac_response()
commit 7dc357d343f134bf59815ff6098b93503ec8a23b upstream.
Dereference auth after NULL check in tpm_buf_check_hmac_response().
Otherwise, unless tpm2_sessions_init() was called, a call can cause NULL
dereference, when TCG_TPM2_HMAC is enabled.
[jarkko: adjusted the commit message.]
Cc: stable@vger.kernel.org # v6.10+
Fixes: 7ca110f2679b ("tpm: Address !chip->auth in tpm_buf_append_hmac_session*()")
