v4l2: v4l2_compat_manager: Store V4L2CameraFile in mmaps_
The mmaps_ map stores a pointer to the V4L2CameraProxy to avoid increasing the reference count on the V4L2CameraFile shared pointer needlessly. While this provides a small optimization, it prevents accessing the V4L2CameraFile from the munmap() function which doesn't take an fd as argument. To prepare for improved debugging that will require access to V4L2CameraFile in munmap(), store the V4L2CameraFile pointer in mmaps_.
