ipv6: explicitly initialize udp6_addr in udp_sock_create6()
syzbot reported the use of uninitialized udp6_addr::sin6_scope_id.
We can just set ::sin6_scope_id to zero, as tunnels are unlikely
to use an IPv6 address that needs a scope id and there is no
interface to bind in this context.
For net-next, it looks different as we have cfg->bind_ifindex there
so we can probably call ipv6_iface_scope_id().
Same for ::sin6_flowinfo, tunnels don't use it.
Fixes: 8024e02879dd ("udp: Add udp_sock_create for UDP tunnels to open listener socket")
