btrfs-progs: Add support for tree block operations on fs_info without roots
Since open_ctree_fs_info() now may return a fs_info even without any
roots, modify functions like read_tree_block() to operate with such
fs_info.
This provides the basis for btrfs-find-root to operate on chunk tree
with corrupted fs.
