The changes in "retry login for ISCSI_ERR_HOST_NOT_FOUND" caused
sessions using the iscsi_tcp transport bound to a network iface to fail
to connect due to the host lookup failing (iscsi_tcp hosts are
dynamically allocated per-session).
This marks transports that use a host fixed to a hardware offload device
with "bind_ep_required" and only requires a host lookup before starting
the connection if this flag is set.
