mac80211: Always send a null data frame if TIM bit is set.
If the AP thinks we are in power save state eventhough we are not truly
in that state, it sets the TIM bit and does not send a data frame unless
we send a null data frame to correct the state in the AP.
This might happen if the null data frame for wake up is lost in the air
after we disable power save.
