tracing: Improve message of empty set_ftrace_notrace file
When there's no entry in set_ftrace_notrace, it'll print nothing, but it's better to print something like below like set_graph_notrace does: #### no functions disabled #### Link: http://lkml.kernel.org/p/1402644246-4649-1-git-send-email-namhyung@kernel.org Reported-by: Naoya Horiguchi <n-horiguchi@ah.jp.nec.com> Signed-off-by: Namhyung Kim <namhyung@kernel.org> Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
