IB/ipoib: Use cancel_delayed_work_sync when needed
The work mcast_task can re-queue itself, so instead of doing cancel && flush_workqueue, that still can leave a queued task on the air, use cancel_delayed_work_sync. Also, no need to use lock over the cancel, the original lock was due to bit assignment setting (IPOIB_MCAST_RUN) that is not in use anymore.
