input: reduce the number of superfluous hierarchy events

There's only two reasons for hierarchy events:
- device is added, removed, etc. In this case we want to send the event as
  it happens.
- devices are added in a XIChangeDeviceHierarchy request. In this case we
  only want one event cumulating all changes.
