media: ov13858: Set default fps as current fps
On format change, sometimes, sensor was streaming at a much higher FPS than the default. This was resulting in various problems like frame drops/corruption. Upon format change, set default vblank as current vblank. This will ensure that sensor will start streaming at default fps.
