platform/x86: ideapad-laptop: Make the scope_guard() clear of its scope

First of all, it's a bit counterintuitive to have something like

	int err;
	...
	scoped_guard(...)
		err = foo(...);
	if (err)
		return err;

Second, with a particular kernel configuration and compiler version in
one of such cases the objtool is not happy:

  ideapad-laptop.o: warning: objtool: .text.fan_mode_show: unexpected end of section

I'm not an expert on all this, but the theory is that compiler and
linker in this case can't understand that 'result' variable will be
always initialized as long as no error has been returned. Assigning
'result' to a dummy value helps with this. Note, that fixing the
scoped_guard() scope (as per above) does not make issue gone.

That said, assign dummy value and make the scope_guard() clear of its scope.
For the sake of consistency do it in the entire file.
