There's a patch for btrfsprogs which introduce a new command: btrfslabel
https://patchwork.kernel.org/patch/70701/
You might need to make some changes to merge it with current version,
but the userland-only patch works great for changing unmounted btrfs
filesystem. It works even without the kernel-side patch.
