iscsi: Fix the potential core dump issue for hotplug test case. 



when test hotplug case with large write command which need r2t, after the
device hot removed, the outstanding r2t commands are waitting for data out PDU,
and the primary commands probably already return with error, then the lun
could be deleted, later the related data out PDU will received and try to send
other r2t, this patch make sure the r2t command sent smoothly even the device
hot removed.
