ath9k: bring back direction setting in ath9k_{start_stop}
A regression was introduced in commit id 79d4db1214a ("ath9k: cleanup led_pin initial") that broken the WLAN status led on my laptop with AR9287 after suspending and resuming. Steps to reproduce: * Suspend (laptop) * Resume (laptop) * Observe that the WLAN led no longer turns ON/OFF depending on the status and is always red Even though for my case it only needs to be set to OUT in ath9k_start but for consistency bring back the IN direction setting as well.
