ath9k: use per-device struct for pm_qos_* operations
The ath9k driver uses a shared pm_qos_request_list structure for all
devices. This causes the following warning if more than one device is
present in the system:
WARNING: at kernel/pm_qos_params.c:234 ath9k_init_device+0x5e8/0x6b0()
pm_qos_add_request() called for already added request

---[ end trace 5345fc6f870564a6 ]---
This patch fixes that warning by using a separate pm_qos_request_list
sructure for each device.
