Some drivers don't need the return value of rfkill_set_hw_state(),

For AP mode we must tune ANI specially for 2 GHz and
for 5 GHz. We mask in only the flags we want to toggle
on ath9k_hw_ani_control() through the ah->ani_function
bitmask, this will take care of ignoring changes during

WEP too until we get a proper fix in.
