RFR: 8373475: Unintentional format string in logString of AccessInfo.cpp

[Damon Nguyen]

This update is to fix the potential issue where tmpbuf can be read as a format argument for `fprintf`. I have added a specifier here to avoid this issue since the string from tmpbuf is not guaranteed to not cause issues. This update should make this print more reliable and safe to use.
