librbd: diffs to clone's first snapshot should include parent diffs

If the clone has a backing object created after the snapshot that
overwrites an extent of the parent, the parent diffs within that
extent are not included in the result.

Hammer-specific implementation due to librbd refactoring during the
Infernalis release.
