Another fix for vfio-ccw: make sure it accesses the correct entries
in the pfn_array_table arrays when checking pinned pages.

s390/cio: Fix how vfio-ccw checks pinned pages

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.
