dm raid: fix address sanitizer warning in raid_resume
[ Upstream commit 7dad24db59
]
There is a KASAN warning in raid_resume when running the lvm test
lvconvert-raid.sh. The reason for the warning is that mddev->raid_disks
is greater than rs->raid_disks, so the loop touches one entry beyond
the allocated length.
