igt/gem_eio: Increase wakeup delay for in-flight-suspend
For in-flight-suspend, we need to wait for the GPU hang within
i915_gem_suspend(). This will take 10-20s, which means that the standard
wakeup delay of around 15s may occur before we complete the suspend.
This causes a pm_system_wakeup(), causing dpm_suspend() to return
-EBUSY.
