ath9k: Check WOW triggers properly
This patch makes sure that valid WOW triggers are present before trying to suspend the device. Also, introduce and use ATH_OP_WOW_ENABLED to bypass PCI suspend and clear it in resume(). Signed-off-by: Sujith Manoharan <c_manoha@qca.qualcomm.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
