V4L/DVB (13037): go7007: Revert compatibility code added at the wrong place

Compatibility code is not allowed upstream. While this could
eventually be useful by out-of-tree compilation, directly from
http://linuxtv.org/hg/v4l-dvb

 tree, the compatibility code is at
the wrong place. In a matter of fact, it is not needed at all, since
compat.h already handles such things.
