Normally the debugfs framework will return error pointer with -ENODEV for function calls when DEBUG_FS is not set. batman does not notice this error code and continues trying to create debugfs files and executes more code. We can avoid this code execution by disabling compiling debugfs.c when DEBUG_FS is not set.
