bcachefs: Improve snapshots_seen

Browse source

This makes the snapshots_seen data structure fsck private and improves
it; we now also track the equivalence class for each snapshot id we've
seen, which means we can detect when snapshot deletion hasn't finished
or run correctly (which will otherwise confuse fsck).
