scsi: ufs: core: Changing the status to check inflight

ufshcd_cmd_inflight() is used to check whether or not a command is in
progress.  Make it skip commands that have already completed by changing
the !blk_mq_request_started(rq) check into blk_mq_rq_state(rq) !=
MQ_RQ_IN_FLIGHT.  We cannot rely on lrbp->cmd since lrbp->cmd is not
cleared when a command completes.
