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.
