ipv6: Check GATEWAY in rtm_to_fib6_multipath_config().
In ip6_route_multipath_add(), we call rt6_qualify_for_ecmp() for each
entry. If it returns false, the request fails.
rt6_qualify_for_ecmp() returns false if either of the conditions below
is true:
1. f6i->fib6_flags has RTF_ADDRCONF
2. f6i->nh is not NULL
3. f6i->fib6_nh->fib_nh_gw_family is AF_UNSPEC
1 is unnecessary because rtm_to_fib6_config() never sets RTF_ADDRCONF
to cfg->fc_flags.
2. is equivalent with cfg->fc_nh_id.
3. can be replaced by checking RTF_GATEWAY in the base and each multipath
entry because AF_INET6 is set to f6i->fib6_nh->fib_nh_gw_family only when
cfg.fc_is_fdb is true or RTF_GATEWAY is set, but the former is always
false.
These checks do not require RCU and can be done earlier.
Let's perform the equivalent checks in rtm_to_fib6_multipath_config().
