[PATCH v2] pipeline: rpi: always initialize the embedded buffer in tryRunPipeline

[Elias Naur]

Vc4CameraData::findMatchBuffers may return successfully with a null
embedded buffer, in which case the embedded buffer id would be left
uninitialized.

Without this change, libcamera v0.2.0 usually crashes for me with an
assertion error:

 ipa_base.cpp:397 assertion "it != buffers_.end()" failed in prepareIsp()
