sctp: lack the check for ports in sctp_v6_cmp_addr
[ Upstream commit 40b4f0fd74e46c017814618d67ec9127ff20f157 ]
As the member .cmp_addr of sctp_af_inet6, sctp_v6_cmp_addr should also check
the port of addresses, just like sctp_v4_cmp_addr, cause it's invoked by
sctp_cmp_addr_exact().
Now sctp_v6_cmp_addr just check the port when two addresses have different
family, and lack the port check for two ipv6 addresses. that will make
sctp_hash_cmp() cannot work well.
so fix it by adding ports comparison in sctp_v6_cmp_addr().
