There's a warning message about an unused code. The code that
were using it were commented out, due to a problem causing the
firmware load to fail on the machines we're using for testing.
Change the place where we're commenting the code out, in order
to avoid the warning.
Fixes: 95d1f398c4dc ("media: atomisp: keep the ISP powered on when setting it")
