demux_lavf: update to handle deprecation of `io_close` 

`io_close2` was introduced as a superior replacement for `io_close` in
ffmpeg 5.0, and then deprecated in 6.0. The difference is that
`io_close2` can return errors. In our case, we're just calling through
to the original function anyway, so we don't need to do more than pass
the return value back.
