Perf: only count into inflight IO when successfully sending 



There is a case in high queue depth situation and the IO may be
failed due to no memory. Our perf tool did not recognize this
and always count the IO in the inflight IOs. Thus in the completion,
it waits more than actual IOs to return and the Perf is hanging.
