HID: nintendo: use ida for LED player id

Previously, the leds pattern would just increment with every controller
connected. This wouldn't take into consideration when controllers are
disconnected. The same controller could be connected and disconnected
with the pattern increasing player count each time.

This patch changes it by using an ID allocator in order to assign the
player id, the same way hid-playstation does.
