Ming Lei c1e2b8422b block: fix double account of flush request's driver tag ...

In case of none scheduler, we share data request's driver tag for
flush request, so have to mark the flush request as INFLIGHT for
avoiding double account of this driver tag.

Fixes: 568f270065 ("blk-mq: centralise related handling into blk_mq_get_driver_tag")
