bcachefs: bch_sb.recovery_passes_required
Add two new superblock fields. Since the main section of the superblock is now fully, we have to add a new variable length section for them - bch_sb_field_ext. - recovery_passes_requried: recovery passes that must be run on the next mount - errors_silent: errors that will be silently fixed These are to improve upgrading and dwongrading: these fields won't be cleared until after recovery successfully completes, so there won't be any issues with crashing partway through an upgrade or a downgrade.
