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. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
