QUIC: fixed removal of unused client IDs.
If client ID was never used, its refcount is zero. To keep things simple,
the ngx_quic_unref_client_id() function is now aware of such IDs.
If client ID was used, the ngx_quic_replace_retired_client_id() function
is supposed to find all users and unref the ID, thus ngx_quic_unref_client_id()
should not be called after it.
