Input: atkbd - restore LED state at reconnect

Even though input core tells us to restore LED state and repeat rate
at resume keyboard may be reconnected either by request from userspace
(via sysfs) or just by pulling it from the box and plugging it back in.
In these cases we still need to restore state ourselves.
