[gnome-disk-utility] Use ensure_unused() on its block device before stopping RAID array

[David Zeuthen <davidz src gnome org>]

commit 9de8f0aeca43e12502818a2a1e4577f4057c1954
Author: David Zeuthen <zeuthen gmail com>

    Use ensure_unused() on its block device before stopping RAID array
    
    This way users won't have to unmount/lock whatever is on a device
    before doing stopping the array.
