[totem] screensaver: Only try to inhibit once

    screensaver: Only try to inhibit once
    
    This stops plenty of warnings appearing on the command-line when
    gtk_application_inhibit() fails. It can fail for a number of reasons,
    but the documentation's only hint is:
    If the platform does not support inhibiting or the request failed for
    some reason, 0 is returned.
    
    So only try to disable the screensaver once.
