IB/iser: Have iSER data transaction object point to iSER conn
iSER uses a data transaction object (struct iser_dto) as part of its IB data descriptors (struct iser_desc) management. It also uses a hierarchy of connection structures pointing to each other. A DTO may exist even after the iscsi_iser connection pointed by it is destroyed (eg one that is bound to a post receive buffer which was flushed by the IB HW). Hence DTOs need point to the lowest connection, which is struct iser_conn. Signed-off-by: Erez Zilber <erezz@voltaire.com> Signed-off-by: Roland Dreier <rolandd@cisco.com>
