tpmcrb_transmit() read CRB_CTRL_STS before requesting locality 0.
An AMD Pluton fTPM (like FrameWork Desktop) using the plain CRB start method
reads the control area as all-ones until locality is assigned, so bit 0 looks
like a stuck tpmSts and every command failed with EIO.
With RANDOM_ENABLE_TPM the harvester retries every 10 seconds, so this printed
"Device has Error bit set" forever.
