firewire: cdev: simplify a schedule_delayed_work wrapper
The kernel API documentation says that queue_delayed_work() returns 0
(only) if the work was already queued. The return codes of
schedule_delayed_work() are not documented but the same.
In init_iso_resource(), the work has never been queued yet, hence we
can assume schedule_delayed_work() to be a guaranteed success there.
