fix nhlsel.c warning

Browse Source 
A recent change has resulted in complaints about 'sel' not being
used in
  struct selectionvar *sel = l_selection_check(L, 1);
  struct selectionvar *ret;
  int p = (int) luaL_checkinteger(L, 2);

  lua_pop(L, 1);
  (void) l_selection_clone(L);
  ret = l_selection_check(L, 1);
  selection_filter_percent(ret, p);

This preserves the semantics of that code while getting rid of the
warning, but I have no idea whether it makes any sense.
