According to the btrfs document[1], adding another disk to the existing
btrfs file system is equivalent to create a raid with Raid 1 on Meta,
Raid 0 on Data group (mkfs.btrfs -m raid1 -d raid0).
So just like bug 1809870, we should be able to mount the drive with 'rw'
in degraded mode after wipe out the second disk (unless the data chunk
was destroyed, i.e. wipe out the first disk)
The degraded mount behaviour has been change since commit
