tpm: Do not print an error message when doing TPM auto startup
This is a regression when this code was reworked and made the error
print unconditional. The original code deliberately suppressed printing
of the first error message so it could quietly sense
TPM_ERR_INVALID_POSTINIT.
Fixes: a502feb67b47 ("tpm: Clean up reading of timeout and duration capabilities")
