[PATCH ath-current 2/2] wifi: ath9k_htc: start ANI when an AP interface begins to beacon

[Mehmet Fide]

From: Mehmet Fide <mehmet.fide@xxxxxxxxxxxxxxxxxx>

ath9k_htc_vif_reconfig() re-arms ANI after a channel change when an AP
interface beacons. mac80211 configures the channel before it enables
the beacon, so during a normal AP start that never triggers, and the
start from add_interface that the previous patch removed was cancelled
by the same channel configuration: with hostapd, ANI and the periodic
calibration it drives did not run in AP mode until a later channel
change.

Start ANI when the beacon is enabled. The channel and its calibration
data are in place by then, which is the state vif_reconfig() re-arms
it in, and remove_interface() already stops it with the last AP
interface.

Fixes: a236254c35f0 ("ath9k_htc: Add ANI for AP mode")
