Pull three more md fixes from Neil Brown:
"Hasn't been a good cycle for md has it :-(
The main issue fixed here is a rare race which can result in two
reshape threads running at once, which doesn't end well.
Also a minor issue with a write to a sysfs file returning the wrong
value. Backports to 4.0-stable are indicated"
