Description of problem: lvconvert -m 0 will always take rimage_0 even if it is out-of-sync.

This is a rhel8.6 version of https://bugzilla.redhat.com/show_bug.cgi?id=2133978

See below /dev/mapper/mpathb(1) is flagged as raid (I)mage out-of-sync but is still used to build the linear volume.

Are you sure you want to convert raid1 LV tvg/lvr1 to type linear losing all resilience? [y/n]: y
Logical volume tvg/lvr1 successfully converted.

Version-Release number of selected component (if applicable):
Reported on lvm2-2.02.187-6.el7
But happens in all releases.

How reproducible:
100%

Steps to Reproduce:
1. vgcreate tvg /dev/sdd /dev/sdg
2. lvcreate --type raid1 --mirrors 1 --name lvr1 -l 100%FREE tvg
3. mkfs.xfs /dev/tvg/lvr1
4. mount /dev/tvg/lvr1 /mnt

[lvr1_rmeta_1] tvg ewi-aor--- 4.00m /dev/sdg(0)

8. lvconvert -m 0 tvg/lvr1

lvr1 tvg wi-ao--- 1016.00m /dev/sda(1)

Actual results:

The out-of_sync raid rimage is used to build a linear volume.

Expected results:

The command fails or the in sync rimage is used.

Additional info:

If I run lvconvert against a resyncing raid1 volume it fails, The same should happen in this case or the in-sync rimage used.

The out-of-sync rimage being used caused a customer to lose 2 hours of prod data. If the command failed they could have recovered raid1 before converting!
