ntfs: support large pages in compressed writes
ntfs_compress_write() derives its page count by shifting the compression
block size and assumes that every compression block begins at a page
boundary. This produces a zero page count for small compression blocks on
large-page systems and ignores an in-page compression block offset.
Map every page covering the compression block, pass the in-page offset to
ntfs_write_cb(), and stage uncompressed output in page-aligned pages.
