    drm/i915/selftests: Fix up igt_reset_engine
    
    Now that we skip a per-engine reset on an idle engine, we need to update
    the selftest to take that into account. In the process, we find that we
    were not stressing the per-engine reset very hard, so add those missing
    active resets.
    
    v2: Actually test i915_reset_engine() by loading it with requests.
    
    Fixes: f6ba181ada55 ("drm/i915: Skip an engine reset if it recovered before our preparations")
