Btrfs-progs: let btrfs-image actually work on a balanced fs
We use the read extent buffer infrastructure to read the super block when we are creating a btrfs-image. This works out fine most of the time except when the fs has been balanced, then it fails to map the super block. So we could fix btrfs-image to read in the super in a special way, but thats more code. So instead just check in the eb reading code if we are reading the super and then don't bother mapping the block, just read the actual offset. This fixed some poor guy who was trying to btrfs-image his fs that had been balanced. Thanks, Signed-off-by: Josef Bacik <jbacik@fb.com> Signed-off-by: David Sterba <dsterba@suse.cz>
