Btrfs-progs: recover raid0/raid10/raid5/raid6 metadata chunk
According to the bytenr of the extent buffer record, we can calculate the index
of the stripes, and we also know which device and where we read out the extent
buffer record, that means we can know the relationship between the device extent
and the stripes in the chunk, by this relationship, we can recover the raid0/radi10/
raid5/raid6 metadata chunk.
