It is possible for sensor handles retrieved using
ASensorManager_getDefaultSensor() to become stale if the underlying
binder connection to the sensor service gets reset. This can be
triggered by ASensorManager_createEventQueue(), so any sensor handle
retrieved prior to this call may become stale, resulting in a use-after-
free when the handle is eventually registered with the queue. To avoid
this, the event queue is created before retrieving or registering the
sensor.
