When the driver finds invalid destination MAC for the first
un-reachable target, and before completes the PATH_REQ
operation, set new ep_state to OFFLDCONN_NONE so that
as part of driver ep_poll mechanism, the upper open-iscsi
layer is notified to complete the login process on the
first un-reachable target and thus proceed login to other
reachable targets.
