mac80211: calculate beacon loss time accurately
Instead of using a fixed 2 second timeout, calculate beacon loss interval from the advertised beacon interval and a frame count. With this beacon loss happens after N (default 7) consecutive frames are missed which for a typical setup (100TU beacon interval) is ~700ms (or ~1/3 previous).
