memory_hotplug: drop spurious calls to flush_scheduled_work()

Browse Source 
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().
