This patch fixed my case:
http://www.spinics.net/lists/linux-btrfs/msg38714.html
Thank you! And thank you, Qu Wenruo for the help!!

I tested all blocks that find-root gave - but only the one with generation =
want + 1 gave some possible root items. The btrfsck with --tree-root <that
block> finally fixed my file system. Hooray!

Ciao
