Subject: [PATCH] mm/memblock: remove unnecessary memblock_type variable

We define struct memblock_type *type in the memblock_add_region()
and memblock_reserve_region() functions only for passing it to the
memlock_add_range() and memblock_reserve_range() functions. Let's
remove these variables and will pass a type directly.
