[PATCH 03/23] memblock: Use memblock_reserve() in memblock internal functions

[Tejun Heo]

Make memblock_double_array(), __memblock_alloc_base() and
memblock_alloc_nid() use memblock_reserve() instead of calling
memblock_add_region() with reserved array directly.  This eases
debugging and updates to memblock_add_region().
