md: make sure manual changes to recovery checkpoint are saved.
If you make an array bigger but suppress resync of the new region with
mdadm --grow /dev/mdX --size=max --assume-clean
then stop the array before anything is written to it, the effect of
the "--assume-clean" is lost and the array will resync the new space
when restarted.
So ensure that we update the metadata in the case.
