bcachefs: bch_sb_field_downgrade
Add a new superblock section that contains a list of
{ minor version, recovery passes, errors_to_fix }
that is - a list of recovery passes that must be run when downgrading
past a given version, and a list of errors to silently fix.
The upcoming disk accounting rewrite is not going to be fully
compatible: we're going to have to regenerate accounting both when
upgrading to the new version, and also from downgrading from the new
version, since the new method of doing disk space accounting is a
completely different architecture based on deltas, and synchronizing
them for every jounal entry write to maintain compatibility is going to
be too expensive and impractical.
