mm/truncate: add folio_unmap_invalidate() helper
Add a folio_unmap_invalidate() helper, which unmaps and invalidates a
given folio. The caller must already have locked the folio. Embed the
old invalidate_complete_folio2() helper in there as well, as nobody else
calls it.
Use this new helper in invalidate_inode_pages2_range(), rather than
duplicate the code there.
In preparation for using this elsewhere as well, have it take a gfp_t mask
rather than assume GFP_KERNEL is the right choice. This bubbles back to
invalidate_complete_folio2() as well.
