Subject: SMB3: handle new statx fields
From: Steve French <smfrench@xxxxxxxxx>
commit 6e70e26dc52be62c1f39f81b5f71fa5e643677aa upstream.
We weren't returning the creation time or the two easily supported
attributes (ENCRYPTED or COMPRESSED) for the getattr call to
allow statx to return these fields.
