This patch addresses a number of active I/O shutdown issues related to isert_cmd descriptors being leaked that are part of a completion interrupt coalescing batch. This includes adding logic in isert_cq_tx_comp_err() to drain any associated tx_desc->comp_llnode_batch, as well as isert_cq_drain_comp_llist() to drain any associated isert_conn->conn_comp_llist. Also, set tx_desc->llnode_active in isert_init_send_wr() in order to determine when work requests need to be skipped in isert_cq_tx_work() exception path code. Finally, update isert_init_send_wr() to only allow interrupt coalescing when ISER_CONN_UP.
