btrfs: tree-checker: Add ROOT_ITEM check
This patch will introduce ROOT_ITEM check, which includes:
- Key->objectid and key->offset check
Currently only some easy check, e.g. 0 as rootid is invalid.
- Item size check
Root item size is fixed.
- Generation checks
Generation, generation_v2 and last_snapshot should not be greater than
super generation + 1
- Level and alignment check
Level should be in [0, 7], and bytenr must be aligned to sector size.
- Flags check
