tplink-safeloader: ignore NULLs in version info

When the soft-version partition contents are checked for a text-format
version string, isascii() is used to check the contained bytes. This
also returns true on control characters, which includes terminating
NULL characters.

After checking if the data is a string, use the actual string length for
printing the contained data to avoid outputting NULLs to stdout.
