bcachefs: Improve fsck for subvols/snapshots

Browse source

- Bunch of refactoring, and move some code out of
   bch2_snapshots_start() and into bch2_snapshots_check(), for constency
   with the rest of fsck

 - Interior snapshot nodes no longer point to a subvolume; this is so we
   don't end up with dangling subvol references when deleting or require
   scanning the full snapshots btree.
