Just want the code to be easy reading.

perf_time__range_skip_sample doesn't allow the invalid time range.

But perf_time__skip_sample allows the time range to be invalid (ptime->start or ptime->end can be 0).

I don't want to mix them up because the code might be not clear.

Are 2 calls OK here? If you think a single call is better, I will change.

Thanks
