V4L/DVB: IR: replace workqueue with kthread
It is perfectly possible to have ir_raw_event_work
running concurently on two cpus, thus we must protect
it from that situation.
This stems from the fact that if hardware sends short packets of samples
we might end up queueing the work item more times that nessesary.
Such job isn't well suited for a workqueue, so use a kernel thread.
