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() and uvc_uninit_video() to
uvc_video_stop().
