device: clear queued_state callback in dispose

dispose() calls _cleanup_generic_pre() which in turn already calls
nm_device_queued_state_clear(). So we would expect that at the end
of dispose() no queued-state is pending.

However, there there are crashes reports in queued_set_state() with the
device instance already destructed (rh#1270247). Add this check trying
to avoid the crash and closing in on the cause.
