memory_hotplug: drop spurious calls to flush_scheduled_work()
lru_add_drain_all() uses schedule_on_each_cpu() which is synchronous.
There is no reason to call flush_scheduled_work() after
lru_add_drain_all(). Drop the spurious calls.
This is to prepare for the deprecation and removal of
flush_scheduled_work().
