Fix a couple of problems in my 1st fix for PIM nexthops reachable via a
connected route:
Use NEXTHOP_TYPE_IPV4_IFINDEX instead of NEXTHOP_TYPE_IPV4 since we add an
IPv4 address to an already known ifindex.
Assign nexthop_tab[num_ifindex].protocol_distance and .route_metric before
incrementing num_ifindex.
Revert the default: to individual switch case statement conversion in
zclient_read_nexthop() as requested by donaldsharp in #2347
