mkvmerge: don't try to relocate written data when discarding relocate_written_data is called in the following situation: * track headers need to be re-written * at least one frame has been written already * the space left right after the track headers does not suffice to expand the track headers In such a case all frames that have been written already will be moved. However, in certain split modes then current file may actually be a null I/O, meaning that the current output is discarded. A null I/O object doesn't return anything when reading for it, causing an endless loop in the relocation code which calls `read` as often as needed until everything's been read — which can never happen with a null I/O object. However, it makes no sense to try to actually read the data in such a case, as it will be discarded anyway. Therefore just avoid trying to read the data in the first place.
