This code has the same behavior of tpm2_get_pcr_allocation(). If some
banks are not used, set the algorithm of the first unused to
TPM_ALG_ERROR.

My point is that maybe it would sense to use zero for that in order
to make code a bit simpler.

Wouldn't be better to compare data with the same type? Since the alg_id
structure member stores an algorithm, it should be fine to compare its
value with an algorithm.

No problem to change that, but probably I should modify also
tpm_pcr_extend().
