The iscsi target core teardown sequence calls wait_conn for all active commands to finish gracefully by: - move the queue-pair to error state - drain all the completions - wait for the core to finish handling all session commands However, when tearing down a session while there are sequenced commands that are still waiting for unsolicited data outs, we can block forever as these are missing an extra reference put. We basically need the equivalent of iscsit_free_queue_reqs_for_conn() which is called after wait_conn has returned. Address this by an explicit walk on conn_cmd_list and put the extra reference.
