tipc: eliminate redundant fields in struct tipc_sock
We eliminate the redundant fields conn_type and conn_instance in
struct tipc_sock. On the connecting side, this information is already
present in the unused (after the connection is established) part of
the pre-allocated header, and on the accepting side, we put it there
when the new socket is created.
