fs/ntfs3: return folios from ntfs_lock_new_page()

ntfs_lock_new_page() currently returns a struct page * but it primarily
operates on folios via __filemap_get_folio(). Convert it to return a
struct folio * and use folio_alloc() + __folio_set_locked() for the
temporary page used to avoid data corruption during decompression.

When the cached folio is not uptodate, preserve the existing behavior by
using folio_file_page() and converting the returned page back to a
folio.

Update ni_readpage_cmpr() and ni_decompress_file() to handle the new
return type while keeping the existing struct page * array and the
unlock_page()/put_page() cleanup paths unchanged.
