security/tpm/tspi: Set return type of tcpa_log_add_table_entry as void
Change f849972 (security/vboot: Enable TCPA log extension) enabled support for adding TCPA log to CBMEM. However, if CBMEM is not online, this function doesn't do anything and returns early. This condition is not really a valid error condition as it depends on when the call to tcpa_log_add_table_entry is made. Since tcpa_log_add_table_entry returns -1 when cbmem is not online, tpm_extend_pcr prints an error message with prefix "ERROR:". This can confuse any scripts trying to catch errors in boot flow. This CL makes the following changes: 1. Removes the print in tpm_extend_pcr since tcpa_log_add_table_entry already prints out appropriate ERROR messages in case of failure to add log entry. 2. Since the return value of tcpa_log_add_table_entry is not used anymore, return type for tcpa_log_add_table_entry is changed to void.
