ipv6_rpl_srh_rcv() checks if ipv6_hdr(skb)->daddr or ohdr->rpl_segaddr[i] is the multicast address with ipv6_addr_type(). We have the same check for ipv6_hdr(skb)->daddr in ipv6_rthdr_rcv(), so we need not recheck it in ipv6_rpl_srh_rcv(). Also, we should use ipv6_addr_is_multicast() for ohdr->rpl_segaddr[i] instead of ipv6_addr_type().
