This is the case when iscsid gets re-launched due to features like
iSCSI boot which requires the daemon to re-launch due to
pivot root. If the code detected the connection had an existing
endpoint, the old endpoint must get cleaned up.

Don't you still leak what bnx2i_free_ep frees?
In userspace you should have iscsid/iscsi_sync_session match the iscsi
endpoint with the iscsi conn and set transport_ep_handle. ep_disconnect
will then get called like normal to clean up the old connection.
