mm/zsmalloc: use memcpy_from/to_page whereever possible

As part of "zsmalloc: replace kmap_atomic with kmap_local_page" [1] we
replaced kmap/kunmap_atomic() with kmap_local_page()/kunmap_local().

But later it was found that some of the code could be replaced with
already available apis in highmem.h, such as
memcpy_from_page()/memcpy_to_page().

Also, update the comments with correct api naming.
