in old times the domain range was defined by a domain_bits le32. This was then converted into a domain_range struct. During the upgrade the original value of '32' (bits) has been kept while the end field now is the max value of the domain id (UINT32_MAX). Fix that and also use UINT64_MAX for the input_range.end.
