The stolen reset selftests (igt_reset_device_stolen and
igt_reset_engines_stolen) poison the unused stolen pages, reset the GPU
and check that those pages did not change. This series fixes two races
in the test itself. Neither one is a GPU reset problem.

v4 -> v5:
- Hold stolen_lock across the reset too (patch 1)
- Add patch 2, which takes ggtt->error_mutex in the test
