media: rc: oops in ir_timer_keyup after device unplug

Browse source

If there is IR in the raw kfifo when ir_raw_event_unregister() is called,
then kthread_stop() causes ir_raw_event_thread to be scheduled, decode
some scancodes and re-arm timer_keyup. The timer_keyup then fires when
the rc device is long gone.
