[patch 050/115] mm/memory_hotplug.c: remove unused local zone_type from __remove_zone()

[akpm]

From: John Hubbard <jhubbard@nvidia.com>
Subject: mm/memory_hotplug.c: remove unused local zone_type from __remove_zone()

__remove_zone() sets up up zone_type, but never uses it for anything. 
This does not cause a warning, due to the (necessary) use of
-Wno-unused-but-set-variable.  However, it's noise, so just delete it.
