When the rdma device is removed, we must cleanup all the rdma resources within the DEVICE_REMOVAL event handler to let the device teardown gracefully. When this happens with live I/O, some memory regions are occupied. Thus, track them too and dereg all the mr's. We are safe with mr access by iscsi_iser_cleanup_task.
