tpm.c: Don't try to put -1 in a variable of type TpmModel
The TpmModel type is an enum (valid values 0 and 1), which means
the compiler can legitimately decide that comparisons like
'tpm_models[i] == -1' are never true. (For example it could
pick 'unsigned char' as its type for representing the enum.)
Avoid this issue by using TPM_MODEL_MAX to mark entries in
the tpm_models[] array which aren't filled in, instead of -1.
This silences a clang warning:
tpm.c:43:27: error: comparison of constant -1 with expression of type
'enum TpmModel' is always false [-Werror,-Wtautological-constant-out-of-range-compare]
if (tpm_models[i] == -1) {
