scsi: Revert "scsi: iscsi: Fix HW conn removal use after free"

This reverts commit c577ab7ba5f3bf9062db8a58b6e89d4fe370447e.

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.
