TPM_E_DOING_SELFTEST

TPM_E_DOING_SELFTEST means the TPM is currently running a full self-test and cannot process the requested command yet.

Treat the status as temporary and retry after the self-test has completed.
Avoid parallel retry loops that continually submit commands while the TPM is busy.
If the status persists across a reboot or for an abnormal time, collect TPM logs and investigate firmware or hardware health.
