When we get a multicast route, the rtm_type is RTN_MULTICAST, but the
rtm_family may be AF_INET. If we only check the type with RTNL_FAMILY_IPMR,
we will get malformed address. e.g.

+ ip -4 route add multicast 172.111.1.1 dev em1 table main

Before fix:
+ ip route list type multicast table main
multicast ac6f:101:800:400:400:0:3c00:0 dev em1 scope link

After fix:
+ ip route list type multicast table main
multicast 172.111.1.1 dev em1 scope link
