If object is on boundary of page, zs_map_object() copy content of object

we can avoid this copy overhead.
This patch implement two API and these get information of memcpy region.
Now, we have newly introduced APIs which reduce copy overhead of
zsmalloc for objects on page boundary.
So use it in zram.
