ath9k: unset the default LED pin if used by platform leds

Browse Source 
Unset the default LED gpio pin if the same gpio pin is used by a LED
defined via platform LED. This prevents that the default led trigger
gets assigned to this LED and the GPIO value gets changed on
wifi up/down in case the led is not used for signaling the wifi state.
