blk-mq: do not update io_ticks with passthrough requests
Flush or passthrough requests are not accounted as normal IO in completion.
To reflect iostat for slow IO, io_ticks is updated when stat show called
based on inflight numbers.
It may cause inconsistent io_ticks calculation result.
So do not account non-passthrough request when check inflight.
