inet_diag: Switch the _dump to work with new header

Make inet_diag_dumo work with given header instead of calculating
one from the nl message.

The SOCK_DIAG_BY_FAMILY just passes skb's one through, the compat code
converts the old header to new one.

Also fix the bytecode calculation to find one at proper offset.
