[GIT PULL REQUEST] md fixes for late 4.0-rc

Hi Linus,
 two regression fixes for md, one fairly recent and minor (diskstats has 
 confusing data) and one older and more serious - RAID0 with non-power-of-2
 chunksize corrupts data.  I guess (almost) no-one uses non-power-of-2 chunks.

Thanks,
NeilBrown

So the pull request obviously came in after I had already tagged and
pushed out 4.0. I've pulled it now.

Both of them were marked for stable, so they'll make 4.0.x eventually
without any further action.
