ntfs: fix initialized size and page state after compressed writes

Browse source

The write iterator now expands attributes before calling
ntfs_compress_write(), so compressed writes must not expand the
attribute themselves. However, the compressed path still needs to reject
zero-byte iterator copies, advance initialized_size after successful I/O,
and invalidate modified folios after a failed compression-unit write.
Reject no-progress copies, persist the new initialized size on success,

and clear folio uptodate state when the synchronous write fails.
