iseries_veth: don't use flush_scheduled_work()
flush_scheduled_work() is on its way out. Remove its usage from
iseries_veth.
* Cancelling a delayed work, queueing it for immediate execution if
cancelled and then waiting for completion can be done by simply
calling flush_delayed_work_sync().
* Explicitly cancel cnx->statemachine_wq on module unload.
