[PATCH net-next 3/3] sctp: Replace sockaddr with sockaddr_inet in sctp_addr union

[Kees Cook]

As part of the removal of the variably-sized sockaddr for kernel
internals, replace struct sockaddr with sockaddr_inet in the sctp_addr
union.

No binary changes; the union size remains unchanged due to sockaddr_inet
matching the size of sockaddr_in6.
