[PATCH BlueZ v1 3/4] shared/bap: Fix not setting metadata

[Luiz Augusto von Dentz <luiz.dentz@gmail.com>]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

bt_bap_stream_metatada shall not send Update Metadata if the states
don't allow it, instead it shall store it so it can be send later when
enabling the stream.
