When pinging an IPv6 link-local address, the reflected packet had
::1 as source address. It should be the link-local address of the
attached interface. The rtalloc() in icmp6_reflect() did not find
the correct local address. The IPv6 routing table does not use
sin6_scope_id, but the embedded scope. So do not recover the scope.
