Add open_ctree_fs_info for partial FS opens
fsck needs to be able to open a damaged FS, which means open_ctree needs to be able to return a damaged FS. This adds a new open_ctree_fs_info which can be used to open any and all roots that are valid. btrfs-debug-tree is changed to use it. Signed-off-by: Chris Mason <>
