vinyl: fix compaction crash on disk read error

`vy_slice_stream_next()` clears the return value on failure. This isn't
expected by `vy_write_iterator_merge_step()`, which doesn't update
the source position in the `vy_wirte_iterator::src_heap` in this case.
As a result, an attempt to remove `end_of_key_src` from the heap in
`vy_write_iterator_build_history()` may crash as follows:

```

Normally, a function shouldn't update the return value on failure so
let's fix `vy_slice_stream_next()`.

Closes #10555
