net: sctp: fix initialization of local source address on accepted ipv6 sockets

commit efe4208: 'ipv6: make lookups simpler and faster' broke initialization of local source address on accepted ipv6 sockets. Before the mentioned commit receive address was copied along with the contents of ipv6_pinfo in sctp_v6_create_accept_sk. Now when it is moved, it has to be copied separately. This also fixes lksctp's ipv6 regression in a sense that test_getname_v6, TC5 - 'getsockname on a connected server socket' now passes.
