libcamera: v4l2_videodevice: Handle unexpected buffers
A kernel bug can lead to unexpected buffers being dequeued where we
haven't entered the buffer in our queuedBuffers_ list.
This causes invalid accesses if not handled correctly within libcamera,
and while it is a kernel issue, we must protect against unpatched
kernels.
Handle unexpected buffers by returning a nullptr, and move cache
management after the validation of the buffer.
