If a station interface is already assigned to a context and is active and a second interface of type AP is added, then beaconing on the new interface has to be begin only after the BSS_CHANGED_BEACON_ENABLED flag is sent by mac80211 to the driver. But, since we issue ATH_CHANCTX_EVENT_ENABLE_MULTICHANNEL as soon as a new channel context is added, a switch occurs almost immediately before BSS_CHANGED_BEACON_ENABLED is received. When a HW reset is done for the new context, beacons are enabled for the interface since "enable_beacon" in the BSS config maintained in mac80211 is true - but the driver hasn't been notified yet. This causes a panic, since the beacon interval is zero for this interface and ath9k_cmn_beacon_config_ap() doesn't have a safety check. Fix this panic by checking if the beacon params has been cached for this context and use the "enable_beacon" flag maintained locally in the driver. Also, recalculate the summary data after the beacon params have been cached when BSS_CHANGED_BEACON_ENABLED is received.
