perf probe: Enable to put probe inline function call site

Enable to put probe inline function call site. This will increase line-based
probe-ability.

<Without this patch>
$ ./perf probe -L schedule:48
<schedule:48>
                pre_schedule(rq, prev);

     50         if (unlikely(!rq->nr_running))
                        idle_balance(cpu, rq);

                put_prev_task(rq, prev);
                next = pick_next_task(rq);

     56         if (likely(prev != next)) {
                        sched_info_switch(prev, next);
                        trace_sched_switch_out(prev, next);
                        perf_event_task_sched_out(prev, next);
