    Fix reverse_upsize_quota_delta attempt to look up deleted flavors

    When we did the "great flavor migration of 2015" we missed a quota method
    which still looks up flavors by id from the migration. Now that flavors
    are moved to the api database and actually removed when deleted, this no
    longer works. The problem manifests itself as a failure when trying to
    revert a migration or resize operation when the original flavor has been
    deleted.
