PATCH 1/2 SCTP: Do not enable peer IPv6 address support on PF_INET

If socket is create by PF_INET type, it can not used IPv6 address to send/recv DATA, So we can not used IPv6 address even if peer tell us it support IPv6 address.
This patch fix to only enabled peer IPv6 address support on PF_INET6 socket.
