fs/ntfs3: Add missing direct_IO in ntfs_aops_cmpr
[ Upstream commit 8b26c8c376b29cf29710fbfd093df194cefe26ad ]
The ntfs3 can use the page cache directly, so its address_space_operations
need direct_IO. Exit ntfs_direct_IO() if it is a compressed file.
Fixes: b432163ebd15 ("fs/ntfs3: Update inode->i_mapping->a_ops on compression state")
Reported-by: syzbot+e36cc3297bd3afd25e19@syzkaller.appspotmail.com
Closes: https://syzkaller.appspot.com/bug?extid=e36cc3297bd3afd25e19
