5.15-stable review patch. If anyone has any objections, please let me know.

[ 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.
