    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.

    Fixes: 86d73312 ("block: update io_ticks when io hang")
