[PATCH] tracing: Fix code comment for ftrace_ops_get_func

[Chunyu Hu]

There is no function 'ftrace_ops_recurs_func' existing in the code, it
should be ftrace_ops_assist_func. Fix the comment to avoid misleading.

Applied, thanks!

I'm not sure it will go in this merge window. It might, I'll have to
see what else there is.
