This refactors the additions to both mctp_dump_addrinfo(), and mctp_rtm_getneigh() - two cases where we're calling nlh_data() on an an incoming netlink message, without a prior nlmsg_parse(). For the neigh.c case, we cannot hit the failure where the nlh does not contain a full ndmsg at present, as the core handler (net/core/neighbour.c, neigh_get()) has already validated the size through neigh_valid_req_get(), and would have failed the get operation before the MCTP hander is called. However, relying on that is a bit fragile, so apply the nlmsg_payload refector here too.
