H A Drelocation.c64c043de Mon May 25 04:30:15 CDT 2015 Liu Bo <bo.li.liu@oracle.com> 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.
