OK, but the ioctl should only be possible when the frontend device is
opened with O_RDWR/O_WRONLY (like for FE_SET_FRONTEND), and the defaults
should be restored when the file descriptor is closed (so that it's not
possible for one app to mess up things for other apps).

It might be a better idea to just temporarily disable zigzag after diseqc
until FE_SET_FRONTEND instead of "losing lock".
