blk-mq: count allocated but not started requests in iostats inflight
In the legacy block case, we increment the counter right after we allocate the request, not when the driver handles it. In both the legacy and blk-mq cases, part_inc_in_flight() is called from blk_account_io_start() right after we've allocated the request. blk-mq only considers requests started requests as inflight, but this is inconsistent with the legacy definition and the intention in the code. This removes the started condition and instead counts all allocated requests.
