Review comment:
If any badRecordException is happened, `structFilters.skipRow` is not
ran for that index and some predicates might not be with all references set in
the row. That's said we could fail to filter out some rows in the case. I guess
that it is fine because we should have Filter on top of Json scan operator to
catch them. <del>Seems we can skip `structFilters.skipRow` once any
badRecordException is happened?</del> Nvm, we still need to evaluate predicates
on other indexes.
