Subject: ath9k: Fix LED polarity for some Mini PCI AR9220 MB92 cards.

From: Vittorio Gambaletta (VittGam) <linux-wireless@vittgam.net>

commit 0f9edcdd88a993914fa1d1dc369b35dc503979db upstream.

The Wistron DNMA-92 and Compex WLM200NX have inverted LED polarity
(active high instead of active low).

The same PCI Subsystem ID is used by both cards, which are based on
the same Atheros MB92 design.
