net/ipv6: Handle onlink flag with multipath routes

For multipath routes the ONLINK flag can be specified per nexthop inrtnh_flags or globally in rtm_flags. Update ip6_route_multipath_addto consider the ONLINK setting coming from rtnh_flags. Each loop overnexthops the config for the sibling route is initialized to the globalconfig and then per nexthop settings overlayed. The flag is 'or'ed intofib6_config to handle the ONLINK flag coming from either rtm_flags orrtnh_flags.Fixes:fc1e64e ("net/ipv6: Add support for onlink flag")Signed-off-by: David Ahern <dsahern@gmail.com>Signed-off-by: David S.
