[PATCH v1 1/3] libcamera: pipeline: virtual: Simplify error return

[Kieran Bingham]

Quoting Barnabás Pőcze (2025-02-03 10:43:24)
> Just return an `std::unique_ptr` constructed from an empty
> initializer instead of doing a `reset()` on the existing
> `config` variable and returning that. This is simpler.
