ipv4: use rcu_assign_pointer() in rt_flush_dev()

rt_flush_dev() replaces rt->dst.dev with blackhole_netdev on uncached
routes.  The field is also exposed as dst.dev_rcu, and existing readers
use dst_dev_rcu().

Use rcu_assign_pointer() for the replacement, as dst_dev_put() already
does for the same field.
