cifs: update FSCTL definitions
Add some missing defines used by ksmbd to the client version of smbfsctl.h, and add a missing newer define mentioned in the protocol definitions (MS-FSCC). This will also make it easier to move to common code. Reviewed-by: Ronnie Sahlberg <lsahlber@redhat.com> Signed-off-by: Steve French <stfrench@microsoft.com>
