Earlier versions of the Linux kernel added a NULL byte to the end of the SSID to enable easy printing of the SSID on the console or in a terminal, but this behavior was problematic (SSIDs are simply byte arrays, not strings) and thus was changed.
This function compensates for that behavior at the cost of some compatibility with odd SSIDs that may legitimately have trailing NULLs, even though that is functionally pointless.
