ntfs: reject direct I/O reads of encrypted files
ntfs_file_read_iter() refuses direct I/O for compressed and WOF
compressed attributes but lets encrypted ones reach iomap_dio_rw().
ntfs_read_iomap_begin_non_resident() has no NInoEncrypted() test, so it
reports IOMAP_MAPPED for the attribute's real clusters and the raw
on-disk ciphertext is copied to the caller. Buffered reads are refused
by ntfs_read_folio(), but direct I/O never calls it.
Fixes: 9c87959601e8 ("ntfs: update file operations")
