1. Fresh install Ubuntu server 22.04.3
2. Create a container via below command:
# mdadm -C /dev/md0 /dev/nvme0n1 /dev/nvme1n1 -n 2 -e imsm
3. It will fail during removing a device from container /dev/md0
 # mdadm -r /dev/md0 /dev/nvme0n1
  mdadm: /dev/nvme0n1 does not appear to be an md device
 # mdadm /dev/md0 -r /dev/nvme0n1
  ==> No output

It can pass via "mdadm --remove /dev/md0 /dev/nvme0n1"

It is a mdadm issue begin commit 546047688e1c64638f462147c755b58119cabdc8, the following commit has fixed it, please help backport it, thanks.
