[PATCH 1/1] mm: remove unused zone_type variable from __remove_zone()

[john.hubbard@gmail.com]

From: John Hubbard <jhubbard@nvidia.com>

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