This patch fixes 2 issues in RFKILL:
* Calling wiphy_rfkill_stop_polling() in ath9k_stop
would mean that the driver cannot report HW status
when the radio is re-enabled. Move this to ath_detach().
* Calling ath_radio_{enable/disable} without checking the current
state results in ath_radio_enable() being called repeatedly
for every invocation of rfkill_poll(). This is not needed
in any case since wiphy_rfkill_set_hw_state() would call
->stop() if the radio has been disabled.
