ivtv: use kthread_worker instead of workqueue
Upcoming workqueue updates will no longer guarantee fixed workqueue to
worker kthread association, so giving RT priority to the irq worker
won't work. Use kthread_worker which guarantees specific kthread
association instead. This also makes setting the priority cleaner.
