This reverts commitc577ab7ba5. The invocation of iscsi_put_conn() in iscsi_iter_destory_conn_fn() is used to free the initial reference counter of iscsi_cls_conn. For non-qla4xxx cases, the ->destroy_conn() callback (e.g., iscsi_conn_teardown) will call iscsi_remove_conn() and iscsi_put_conn() to remove the connection from the children list of session and free the connection at last. However for qla4xxx, it is not the case. The ->destroy_conn() callback of qla4xxx will keep the connection in the session conn_list and doesn't use iscsi_put_conn() to free the initial reference counter. Therefore, it seems necessary to keep the iscsi_put_conn() in the iscsi_iter_destroy_conn_fn(), otherwise, there will be memory leak problem.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
