This patch protects against data corruption that could happen in the bus,
by checking that that the digest size returned by the TPM during a PCR read
matches the size of the algorithm passed to tpm2_pcr_read().
This check is performed after information about the PCR banks has been
retrieved.

Before this patch set, tpm2_pcr_extend() always copied 20 bytes from the
output sent by the TPM.
