drivers: video: Fix skipped CIDs when enumerating controls

When enumerating controls with VIDEO_CTRL_FLAG_NEXT_CTRL, if child devices
have controls with IDs lower or equal to the ones in the parent devices,
those controls will be accidentally skipped.

Fix this by resetting the query's ID and tracking of the queried device in
the query when moving to the next device in the pipeline.
