dm: convey that all flushes are processed as empty
Rename __clone_and_map_flush to __clone_and_map_empty_flush for added
clarity.
Simplify logic associated with REQ_FLUSH conditionals.
Introduce a BUG_ON() and add a few more helpful comments to the code
so that it is clear that all flushes are empty.
Cleanup __split_and_process_bio() so that an empty flush isn't processed
by a 'sector_count' focused while loop.
