dm snapshot: persistent make metadata_wq multithreaded
metadata_wq serves on-stack work items from chunk_io(). Even if
multiple chunk_io() are simultaneously in progress, each is
independent and queued only once, so multithreaded workqueue can be
safely used.
Switch metadata_wq to multithread and flush the work item instead of
the workqueue in chunk_io().
