ath9k: pass the ieee80211_hw on radio enable/disable 

We use the ieee80211_hw for radio enable/disable but the wrong
structure hw was being used in consideration for virtual wiphys
as each virtual wiphy has its own ieee80211_hw struct.

Just pass the hw struct to ensure we use the right one. This should
fix the hw used and passed for radio enable/disable. This includes
the stoping / starting of the software TX queues so mac80211 doesn't
send us data for a specific virtual wiphy. ath9k already takes care
of pausing virtual wiphys and stopping the respective queues on its
own, but this should handle the idle mac80211 conf calls as well.
