[Intel-gfx] [CI 6/8] drm/i915/selftests: Replace an unbounded set-domain wait with a timeout

[Chris Wilson]

After the memory-region test completes, it flushes the test by calling
set-to-cpu-domain. Use the igt_flush_test as it includes a timeout,
recovery and reports and error for miscreant tests.
