Liu Bo 64c043de46 Btrfs: fix up read_tree_block to return proper error ...

The return value of read_tree_block() can confuse callers as it always
returns NULL for either -ENOMEM or -EIO, so it's likely that callers
parse it to a wrong error, for instance, in btrfs_read_tree_root().

This fixes the above issue.
