media: uvcvideo: Rename uvc_{un,}init_video()
We have both uvc_init_video() and uvc_video_init() calls which can be quite confusing to determine the process for each. Now that video uvc_video_enable() has been renamed to uvc_video_start_streaming(), adapt these calls to suit the new flow. Rename uvc_init_video() to uvc_video_start_transfer() and uvc_uninit_video() to uvc_video_stop_transfer().
