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().
