Nicholas Bellinger d8bd97a03c iscsi/iser-target: Fix isert_conn->state hung shutdown issues ... commit defd884845 upstream. This patch addresses a couple of different hug shutdown issues related to wait_event() + isert_conn->state. First, it changes isert_conn->conn_wait + isert_conn->conn_wait_comp_err from waitqueues to completions, and sets ISER_CONN_TERMINATING from within isert_disconnect_work(). Second, it splits isert_free_conn() into isert_wait_conn() that is called earlier in iscsit_close_connection() to ensure that all outstanding commands have completed before continuing. Finally, it breaks isert_cq_comp_err() into seperate TX / RX related code, and adds logic in isert_cq_rx_comp_err() to wait for outstanding commands to complete before setting ISER_CONN_DOWN and calling complete(&isert_conn->conn_wait_comp_err).
