drm/panfrost: Fix a page leak in panfrost_mmu_map_fault_addr() when THP is on
drm_gem_put_pages(), which we rely on for returning BO pages to shmem,
assume per-folio refcounting and not per-page. If we call
shmem_read_mapping_page() per-page, we break this assumption and leak
pages every time we get a huge page allocated.
v2:
- Rework the logic for() loop to better match the folio-granular
allocation scheme
