folio_has_private() is an attractive nuisance; filesystem authors
generally don't realise that it actually checks two flags (one of which
is never set by bcachefs).  There's no need to check the private flag at
all; for folios owned by bcachefs, we know that folio->private is NULL
when the private flag is clear and non-NULL when the private flag is set.
