Seek beyond the end will now directly return an error instead
of claiming to succeed and then return EOF immediately on next read.
This change is because before 47e015e6f1
mkv seek incorrectly never failed.

As far as I could see the only change is increased pos values,
which is as expected with additional metadata in the files.
