zsmalloc: zs_object_copy: add clarifying comment

Patch series "tidy up zsmalloc implementation"

This patchset remove some unnecessary checks and adds a clarifying
comment.  While analysing zs_object_copy() function code, I spent some
time to understand what the call kunmap_atomic(d_addr) is for.  It seems
that this point is not trivial and it is worth adding a comment.


This patch (of 2):

It's not obvious why kunmap_atomic(d_addr) call is needed.
