Xin Long 400b8b9a2a sctp: allocate sctp_sockaddr_entry with kzalloc ...

The similar issue as fixed in Commit 4a2eb0c37b ("sctp: initialize
sin6_flowinfo for ipv6 addrs in sctp_inet6addr_event") also exists
in sctp_inetaddr_event, as Alexander noticed.

To fix it, allocate sctp_sockaddr_entry with kzalloc for both sctp
ipv4 and ipv6 addresses, as does in sctp_v4/6_copy_addrlist().
