Andriy Gapon e84d431622 superio: do not assume that current LDN cannot change after config exit
That assumption should be true when superio(4) uses the hardware
exlusively.  But it turns out to not hold on some real systems.
So, err on the side of correctness rather than performance.
Clear current_ldn in sio_conf_exit.
