[ 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().
