md updates for 4.3

- An assortment of little fixes, several for minor races only likely
to be hit during testing
- further cluster-md-raid1 development, not ready for real use yet.
- new RAID6 syndrome code for ARM NEON
- fix a race where a write can return before failure of one device
is properly recorded in metadata, so an immediate crash might result
in that write being lost.
