mm/memblock.c: make memblock_overlaps_region() return bool.
memblock_overlaps_region() checks if the given memblock region intersects a region in memblock. If so, it returns the index of the intersected region. But its only caller is memblock_is_region_reserved(), and it returns 0 if false, non-zero if true. Both of these should return bool.
