Uhh, just do btrfs-find-root by itself to get everything it can find.
And then work backwards from the most recent generation using btrfs
restore -t using each root bytenr from btrfs-find-root. The more
recent the generation, the better your luck that it hasn't been
overwritten yet; but too recent and your data may not exist in that
root. It really depends how fast you umounted the volume after
deleting everything.
