[IPV4]: Fix nexthop realm dumping for multipath routes
Routing realms exist per nexthop, but are only returned to userspace for the first nexthop. This is due to the fact that iproute2 only allows to set the realm for the first nexthop and the kernel refuses multipath routes where only a single realm is present. Dump all realms for multipath routes to enable iproute to correctly display them. Signed-off-by: Patrick McHardy <kaber@trash.net> Signed-off-by: David S. Miller <davem@davemloft.net>
