I also have got one FS in that same situation. I tried
everything on it including that "restore" (which bailed out with
those same error messages IIRC).

The only thing that got me a bit further was to use an alternate
superblock, though that screwed the FS even further as I need to
reboot the machine after trying to mount it (mount hangs and
there are some btrfs tasks using all the CPU time).

=46ortunately, for that one, I had a not too old backup at the
block device level.
