mounting btrfs filesystem (with possible broken content)

[Pauli]

I have btrfs filesystem in micro-sd card. I had it mounted with sync flag set to record a bug to it. Too bad btrfs code hit BUG() when trying to mount the micro-sd card after I hit the bug.

It is possible that I pulled power off the device while it was writing to the card.
