Input: wacom - put a flag when the led are initialized
This solves a bug with the wireless receiver: - at plug, the wireless receiver does not know which Wacom device it is connected to, so it does not actually creates all the LEDs - when the tablet connects, wacom->wacom_wac.features.type is set to the proper device so that wacom_wac can understand the packets - when the receiver is unplugged, it detects that a LED should have been created (based on wacom->wacom_wac.features.type) and tries to remove it: crash when removing the sysfs group. Side effect, we can now safely call several times wacom_destroy_leds().
