iwlagn: update beacon smarter
Updating the beacon every time right after one was transmitted is pointless, most of the time we might not even have to update it. We will update it every time it changes, which includes from set_tim(), a callback iwlwifi didn't implement so far. This also reduces latency for clients, previously we would update the beacon right after the previous one was transmitted, and then a TIM change would only take effect after that again -- updating the beacon right after the TIM changes makes the TIM change go out to the air faster.
