iwlwifi: mvm: don't ask for beacons when AP vif and no assoc sta
When in AP mode, we need beacons from other APs for HT protection. However, when there's no any associated station we will not do any Tx and thus don't really need beacons. On the other hand, these beacons will cause a lot of unnecessary wakeups which increase our power consumption. Handle this by asking FW to pass beacons only when there's at least one associated station.
