In a latter patch, there is a need to update "cb->min_dump_alloc" in inet_sk_diag_fill() as it learns the diffierent bpf_sk_storages stored in a sk while dumping all sk(s) (e.g. tcp_hashinfo). The inet_sk_diag_fill() currently does not take the "cb" as an argument. One of the reason is inet_sk_diag_fill() is used by both dump_one() and dump() (which belong to the "struct inet_diag_handler". The dump_one() interface does not pass the "cb" along. This patch is to make dump_one() pass a "cb". The "cb" is created in inet_diag_cmd_exact(). The "nlh" and "in_skb" are stored in "cb" as the dump() interface does. The total number of args in inet_sk_diag_fill() is also cut from 10 to 7 and that helps many callers to pass fewer args. In particular, "struct user_namespace *user_ns", "u32 pid", and "u32 seq" can be replaced by accessing "cb->nlh" and "cb->skb". A similar argument reduction is also made to inet_twsk_diag_fill() and inet_req_diag_fill(). inet_csk_diag_dump() and inet_csk_diag_fill() are also removed. They are mostly equivalent to inet_sk_diag_fill(). Their repeated usages are very limited. Thus, inet_sk_diag_fill() is directly used in those occasions.
