vf_delogo: copy in non-direct case, fix double-free 

If the image is not writeable, the image actually has to be copied
beforehand. This was overlooked when converting the video chain to
reference counted images.

Fix a double free issue. This was overlooked when vf.c was changed to
free filter priv data automatically.
