fs/proc/task_mmu: use folio API in pte_is_pinned()
Patch series "mm: remove page_maybe_dma_pinned() and page_mkclean()".
Most page_maybe_dma_pinned() and page_mkclean() callers have been
converted to the folio equivalents, after two more convertsions,
remove them and update the comment and documention.
This patch (of 4):
Convert to use vm_normal_folio() and folio_maybe_dma_pinned() API, which
helps to remove page_maybe_dma_pinned() in the subsequent change.
