btrfs-progs: Allow inspect dump-tree to show specified tree block even some tree roots are corrupted
For btrfs inspect-internal dump-tree, if we use "-b" parameter to show
specified tree block, then we don't really need extra tree roots.
Only chunk root is needed to build up the whole chunk mapping so we can
read tree blocks.
This patch will add __OPEN_CTREE_RETURN_CHUNK_ROOT flag when show
speicifed tree block.
So even root tree is corrupted, we can still use inspect-internal
dump-tree to do some debugging.
