Wrong logic in netcdf output determination

In readcommand

#ifdef USE_NCF
  lnetcdfout = 1
#endif
  if (iout.ge.8) then
     lnetcdfout = 1
     iout = iout - 8

This means that if netcdf support is compiled in, netcdf output will be produce even if not set in iout. Delete the first 3 lines of the code snippet.
