staging/lirc_parallel: fix panic on rmmod
lirc_parallel seems to leave a bunch of stuff around after rmmod. Without the patch below modprobe ; rmmod ; modprobe will cause a panic. There are still some remaining problems, (double registration of sysfs files) but this patch is at least a start to survive the panic.
