ipv6: Move nexthop_find_by_id() after fib6_info_alloc().
We will get rid of RTNL from RTM_NEWROUTE and SIOCADDRT.
Then, we must perform two lookups for nexthop and dev under RCU
to guarantee their lifetime.
ip6_route_info_create() calls nexthop_find_by_id() first if
RTA_NH_ID is specified, and then allocates struct fib6_info.
nexthop_find_by_id() must be called under RCU, but we do not want
to use GFP_ATOMIC for memory allocation here, which will be likely
to fail in ip6_route_multipath_add().
Let's move nexthop_find_by_id() after the memory allocation so
that we can later split ip6_route_info_create() into two parts:
the sleepable part and the RCU part.
