Subject: [PATCH v3 1/4] mm/memory-hotplug: Drop unused args from remove_memory_section

From: Oscar Salvador <osalvador@...e.de>

unregister_memory_section() calls remove_memory_section()
with three arguments:

* node_id
* section
* phys_device

Neither node_id nor phys_device are used.
Let us drop them from the function.
