[Intel-gfx] [PATCH] drm/i915/selftests: Fix some error codes

[Dan Carpenter]

These error paths return success instead of negative error codes as
intended.

Fixes: c92724de6db1 ("drm/i915/selftests: Try to detect rollback during batchbuffer preemption")
Fixes: 2d19a71ce68f ("drm/i915/selftests: Exercise long preemption chains")
