mac80211: invoke set_tim() callback after setting own TIM info
Drivers should be allowed to simply get a complete new beacon when set_tim() is invoked (and set_tim() is required for drivers that just want a beacon template!), so we need to update our own TIM bitmap before calling set_tim() so that getting the beacon will now get an already updated beacon.
