btrfs: tree-checker: Add EXTENT_DATA_REF check
EXTENT_DATA_REF is a little like DIR_ITEM which contains hash in its
key->offset.
This patch will check the following contents:
- Key->objectid
Basic alignment check.
- Hash
Hash of each extent_data_ref item must match key->offset.
- Offset
Basic alignment check.
