if conn timeout，we want to call conversation_remove_from_hashtable and free conn,how did i do?

[ygm521]

also did not free any mem.

void
conn_timeout_deal()
{
conversation_t *conn_node = NULL;
struct list_head *pos = NULL, n = NULL;
wmem_map_t hashtable;

if (list_empty(&conn_head_list)) {
	return;
}

struct timeval now;
gettimeofday(&now, NULL);

list_for_each_safe(pos, n, &conn_head_list) {
	conn_node = list_entry(pos, conversation_t, list);
	
	if((now.tv_sec - conn_node->conn_time.tv_sec) < 30) {
	   break;
	}

	if (conn_node->options & NO_ADDR2) {
		if (conn_node->options & (NO_PORT2|NO_PORT2_FORCE)) {
			hashtable = conversation_hashtable_no_addr2_or_port2;
		} else {
			hashtable = conversation_hashtable_no_addr2;
		}
	} else {
		if (conn_node->options & (NO_PORT2|NO_PORT2_FORCE)) {
			hashtable = conversation_hashtable_no_port2;
		} else {
			hashtable = conversation_hashtable_exact;
		}
	}

	conversation_remove_from_hashtable(hashtable, conn_node);
	list_del(pos);

	if (conn_node->key_ptr) {           
		wmem_free(wmem_file_scope(), conn_node->key_ptr);
	}

	if(conn_node->dissector_tree && !wmem_tree_is_empty(conn_node->dissector_tree)) {
		wmem_tree_destroy(conn_node->dissector_tree, FALSE, FALSE);
	}

	wmem_free(wmem_file_scope(), conn_node);
	conn_node = NULL;
}

}
