drm/amd/display: Retain phantom plane/stream if validation fails
[Description]
- If we fail validation, we should retain the phantom
stream/planes
- Full updates assume that phantom pipes will be fully
removed, but if validation fails we keep the phantom
pipes
- Therefore we have to retain the plane/stream if validation
fails (since the refcount is decremented before validation,
and the expectation is that it's fully freed when the old
dc_state is released)
