Update headers to update various SMB3 ioctl definitions
MS-SMB2 Section 2.2.31 lists fsctls. Update our list of valid cifs/smb2/smb3 fsctls and some related structs based on more recent version of docs. Additional detail on less common ones can be found in MS-FSCC section 2.3. CopyChunk (server side copy, ie refcopy) will depend on a few of these Signed-off-by: Steve French <smfrench@gmail.com>
