From: Mike Rapoport (Microsoft) <rppt@kernel.org>

[ Upstream commit 33ea120582a638b2f2e380a50686c2b1d7cce795 ]

The CPA_ARRAY test always uses len[1] as numpages argument to
change_page_attr_set() although the addresses array is different each
iteration of the test loop.

Replace len[1] with len[i] to have numpages matching the addresses array.
