dm: fix missed error code if .end_io isn't implemented by target_type
In bio-based DM's clone_endio(), when target_type doesn't implement .end_io (e.g. linear) r will be always be initialized 0. So if a WRITE SAME bio fails WRITE SAME will not be disabled as intended. Fix this by initializing r to error, rather than 0, in clone_endio().
