The purpose of the sequence generation counter in the netlink callback is to identify if a multipart dump is consistent or not by calling nl_dump_check_consistent() whenever a message is generated. The function is not invoked by the MDB code, rendering the sequence generation counter assignment pointless. Remove it. Note that even the function was invoked, we still could not accurately determine if the dump is consistent or not, as there is no sequence generation counter for MDB entries, unlike nexthop objects, for example.
