tpm: Don't create an EventLog if algorithms are misconfigured

tpm: Don't create an EventLog if algorithms are misconfigured

We already check the active banks vs what U-Boot was compiled with when
trying to extend a PCR and we refuse to do so if the TPM active ones
don't match the ones U-Boot supports.

Do the same thing for the EventLog creation since extending will fail
anyway and print a message so the user can figure out the missing
algorithms.
