man: shorten/reword a bit in sd_bus_get_n_queued_read

In particular:
- drop "when it is non-zero" to avoid implying that it can be called if the
  queue is not empty.
- "has been created" sounds like something happened in parallel,
  but what we really mean is that *this* particular object *was* created in a
  certain way.
