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. Reported-by: Sebastian Riemer <sebastian.riemer@profitbricks.com> Signed-off-by: NeilBrown <neilb@suse.de>
