The DC3CO video playback simulation test was incorrectly using require at
the end to check if DC3CO state was entered. This causes the test to be
marked as SKIP instead of FAIL when DC3CO doesn't work properly, hiding
real issues. So changing the call from require to assert.

Fixes: b89efa8048e58 ("tests/i915/i915_pm_dc: Check dc3co count to skip the test")
