So that we can get the label of a mounted filesystem.
Before this change:
$ btrfs prop get /mnt/btrfs label
ERROR: object is not compatible with property
$ btrfs prop get /dev/sdb3 label
ERROR: dev /dev/sdb3 is mounted, use mount point
ERROR: failed to set/get property for object.
After this change:
$ btrfs prop get /mnt/btrfs label
label=foobar
