libcamera: ipu3: Do not over-write metadata

When a Request is completed upon receiving the IPA produced metadata,
the metadata associated with the Request were over-written, deleting
the information set, in example, at ImgU output buffer completion.

If any additional Request metadata should be registered by inspecting
the IPA produced metadata it has to be done without deleting the already
registered entry.

Fix this by replacing the metadata over-write with a todo entry.

This change fixes CTS which was broken due to missing metadata in
the completed requests.
