Fix race in StaEvents metrics collection A race is happening because one part of StaEventList modification is current unprotected, and we have 2 different threads that trigger StaEventList modifications: - Thread 1: Binder thread -> dump() -> clearing StaEventList - Thread 2: WifiLooper -> addStaEvent() -> may result in removing first element if StaEventList if 'full' Bug: 145163784 Test: atest FrameworksWifiTests Change-Id: Id390bae9a9a661900073195fd1224106a03273ee
