inet_diag: fix possible overflow in inet_diag_dump_one_icsk()

inet_diag_dump_one_icsk() allocates too small skb.

Add inet_sk_attr_size() helper right before inet_sk_diag_fill()
so that it can be updated if/when new attributes are added.

iproute2/ss currently does not use this dump_one() interface,
this might explain nobody noticed this problem yet.
