oops in btrfs listxattr codepath

I'm fairly sure the btrfs rootfs on my laptop is corrupt. I'm trying to salvage it by tarring off the old data and intend to rebuild the fs.

To do that, I booted single user and remounted the rootfs read-only. I then tried using "tar --xattr" to save off xattr info when I tarred it up. That gave me the attached panic.
