sctp: sctp_diag should dump sctp socket type
Now we cannot distinguish that one sk is a udp or sctp style when
we use ss to dump sctp_info. it's necessary to dump it as well.
For sctp_diag, ss support is not officially available, thus there
are no official users of this yet, so we can add this field in the
middle of sctp_info without breaking user API.
v1->v2:
- move 'sctpi_s_type' field to the end of struct sctp_info, so
that it won't cause incompatibility with applications already
built.
- add __reserved3 in sctp_info to make sure sctp_info is 8-byte
alignment.
