We changed read I/O submission to stop splitting when detecting LUN hotplug very recently. We can do the same refinement for read I/O abortion. In _iscsi_conn_abort_queued_datain_task(), set all remaining length to the new task and complete it immediately. We keep the code to process the case that queued_datain_task completed but is still in queue, but we can change its if condition to assert. Simplify the corresponding unit tests accordingly, and set task->scsi.transfer_len in abort_queued_datain_tasks_test() to exercise the changed paths. In iscsi_pdu_payload_po_scsi_read(), if task->scsi.transfer_len is not larger than SPDK_BDEV_LARGE_BUF_MAX_SIZE, no minimum calculation is necessary and we can substitute task->scsi.transfer_len to task->scsi.length simply. This change is too small to be an independent patch and is done together.
