ath9k: fix access to freed data on unload
Calling ath_bus_cleanup() after ieee80211_free_hw() resulted in access
to common->bus_ops, which is already freed as part of the device data.
Remove the cleanup field in struct ath_bus_ops, as it was never used
properly. Remove ath_bus_cleanup(). Merge cleanup functions in place
of the ath_bus_cleanup() calls. Take care not to use any device data
after ieee80211_free_hw().
