dm cache: remove all obsolete writethrough-specific code

commit 9958f1d9a04efb3db19134482b3f4c6897e0e7b8 upstream.

Now that the writethrough code is much simpler there is no need to track
so much state or cascade bio submission (as was done, via
writethrough_endio(), to issue origin then cache IO in series).

As such the obsolete writethrough list and workqueue is also removed.
