setDDMode should set moveKeysLockWriteKey 

After takeMoveKeysLock notes down the owner and the
moveKeysLockWriteKey value, it monitors the above two in
pollMoveKeysLock and checks if anything is changed, but
setDDMode was not setting the moveKeysLockWriteKey and
so a sequence like disable, enable and disable would not
really disable DD.
