[ Upstream commit c44a5ee803d2b7ed8c2e6ce24a5c4dd60778886e ]
Update superblock when particular devices are requested via rebuild
(e.g. lvconvert --replace ...) to avoid spurious failure with the "New
device injected into existing raid set without 'delta_disks' or
'rebuild' parameter specified" error message.
