When CONFIG_SYS_VSNPRINTF is enabled, it protects print operations such as sprintf, snprintf, vsnprintf, etc., from buffer overflows. But vsnprintf_internal includes the terminating NULL character in the calculation of number of characters written. This affects sprintf and snprintf return values. Fix this issue by setting pointer 'str' back to the location of the '\0'.
