btrfs-progs: Refactor read_tree_block to get rid of btrfs_root
The only reasom read_tree_block() needs a btrfs_root parameter is to get its node/sector size. And long ago, I have already introduced a compactible interface, read_tree_block_fs_info() to pass btrfs_fs_info instead of btrfs_root. Since we have cleaned up all root->sector/node/stripesize users, we should be OK to refactor read_tree_block() function. Signed-off-by: Qu Wenruo <>
