If a TPM is in disabled state, it's reasonable for it to have an empty log. Bailing out of probe in this case means that the PPI interface isn't available, so there's no way to then enable the TPM from the OS. In general it seems reasonable to ignore log errors - they shouldn't itnerfere with any other TPM functionality.

Can this be tested with QEMU somehow?

I think you could hack ovmf to disable the event log, but I can't think of a trivial test otherwise.
