    1. Remove device database entry (ddb) state.
    2. Remove device database (DDB) list building.
                    With open-iscsi integration the logins to the target devices are
            handled by the user space. So the information of target is now
            maintained in the iscsi_session object. This is handled at
            libiscsi level so there is no need to maintain a list of DDBs in
            the qla4xxx LLD.
    3. qla4xxx: Remove add_device_dynamically.
                    Since autologin in FW is disabled with open-iscsi integration,
            driver will never get an AEN for which driver has not requested
            a DDB index. So remove the add_device_dynamically function.
    4. Remove qla4xxx_tgt_dscvr
            Since firmware autologin is disabled this function will not work.
            Now user has the ability to do the target discovery and login to
            each target individually. Firwmare will not do the login on its own.
    5. Remove relogin related code
            All relogin is handled by userspace now. qla4xxx just need to
            notify userspace of a connection failure, this triggers the
            relogin.
    6. Remove add_session and alloc_session
            Now qla4xxx uses iscsi_session_setup that would do the necessary
            allocations for session and ddb_entry.
