Currently the iSER receive completion flow takes the session lock twice. Optimize it to avoid the first one by letting iser_task_rdma_finalize() be called only from the cleanup_task callback invoked by iscsi_free_task, thus reducing the contention on the session lock between the scsi command submission to the scsi command completion flows.
