s390/cio: Fix how vfio-ccw checks pinned pages
commit
24abf2901b18bf941b9f21ea2ce5791f61097ae4 upstream.
We have two nested loops to check the entries within the pfn_array_table
arrays. But we mistakenly use the outer array as an index in our check,
and completely ignore the indexing performed by the inner loop.
