We have the block integrity code to support DIF/DIX in the the tree for
about 5 and a half years, and we still don't have a single consumer of
it.  By normal kernel rules it should never have been merged, or at
least the bitrot long removed.

Given that we'll have a lot of work to do in this area with block
multiqueue I think it's time to either kill it off for good or make sure
we can actually use and test it.
